What to do oil leaks in the car sump. What to do if oil is leaking from the engine. Where are engine oil leaks most common?

One of the most common troubles that any car owner can expect is engine oil leakage. It manifests itself first in the appearance of oil streaks, then in more serious stains, and in the final stage it is marked by oil dripping. Such a leak can lead not only to clogging of the propulsion system, but also to its complete failure and even a car fire. Therefore, the appearance of oil stains must be taken seriously. This can also include oil leakage from the gearbox or other similar problems.

If you list the main components of the machine that can be subject to such an unwanted leak, you can make an extensive list. It will include both serious options and those whose solution will not force you to be distracted from driving for a long time. These include:

the appearance of oil on the valve cover, distributor or gasoline pump;
problems in which oil leaks from the automatic transmission;
problems with the crankcase suction tube;
breakdown of the intake manifold geometry control system;
leakage in the area of the oil gauge;
leak in the area of the oil filter;
problems with the engine oil pan;
the same problems, but with the automatic transmission oil pan;
leaking oil seals, etc.

Oil is considered one of the main components of a car to ensure its performance. How to fix an oil leak depends on the cause that led to the leak. Also, the way to eliminate such unpleasant consequences depends on the source of the leak and the parts and components of the machine, which were affected by the oil leak. A visible effect, indicating the beginning of oil leakage, can be the appearance of gray or blue smoke from the exhaust pipe. This may be due to oil leaks from the gearbox or closely spaced components. If gray smoke appears, it is necessary to stop the car and eliminate the consequences of such a leak.

This can be a serious test for every motorist, since it is necessary to have good knowledge to carry out such events. They should concern not only the theoretical part, that is, the internal structure of the car. Practical experience of traveling on Russian roads is also of great importance. If you have similar experience, you can easily determine if oil is leaking from under the valve cover or from other parts of the machine. But even with serious knowledge, it is far from always possible to be sure that you can cope with the misfortune that has fallen on your head on your own.

Significant in this respect is the appearance of blue smoke not from the exhaust pipe, but from under the hood of the car. For any experienced driver, the appearance of blue smoke from under the hood will immediately signal oil leakage problems. The reason may be that oil is leaking from the sump of the engine. In many cases, it will be very difficult for you to cope with such a problem on your own. In such a situation, it is necessary to turn to the services of specialized organizations that are able to deal with such problems.

Signs of an impending crisis can be identified in several ways:

visually, by the appearance of blue smoke;
by smelling, smelling;
for violations in the working rhythm of the engine.

It is also possible to establish an engine oil leak by referring to the oil sensor data. If, while driving, the sensor shows a sharp jump in oil consumption, you can be sure that there is an engine oil leak somewhere. If you want to save your precious time, you shouldn't try to repair the leak yourself. Better call the nearest service station and make an emergency call. You may have to wait a bit (especially if you are outside the city). But on the other hand, you can hope for the qualified help of highly qualified specialists.

You can act independently

If you are confident in your abilities and are able to eliminate the oil leak from the engine, it makes sense to try to repair the leak on your own. If there is a problem with the valve cover, you can remove it and use a sealant. In this case, it is necessary to lubricate not only the rubber seal, but also the shaped washers under the bolts. It is also necessary to clean the oil separator screen, although this is difficult to do without the necessary tools.

If you have problems with the distributor, then you can remove it and lubricate the rubber toric below with sealant. In this case, the flow of engine oil in most cases stops after the distributor returns to its rightful place. If the clogging of the crankcase gas suction tube is to blame for the leak, you can resuscitate its performance. It must be thoroughly cleaned, but with serious wear of the piston group, this is unlikely to help. In this case, only a complete replacement will help out if you have these parts in stock.

How to fix the oil leak, if the oil sensor is to blame for the problem, you can not think for a long time. It must be completely replaced, since in the overwhelming majority of cases it cannot be restored in the event of a breakdown. If the leak is from the automatic transmission oil pan, then it is necessary to replace the old gaskets with new ones. You shouldn't try to restore them - just waste your time.

An article about oil leaks from a car engine - causes, consequences, ways to fix the problem. At the end of the article - a video on how to determine where the oil is flowing from.

Varieties of leakage

If the leaks that you found under the bottom of the car look greasy and are stained dirty brown or yellow, then this is most likely an oil leak from the engine. And with a pinkish or reddish tint of the flowing liquid, we can conclude that this is antifreeze leaving the automatic transmission.

Effects of oil leakage

Oil lubrication for a car is the same as blood for a biological organism, because it is the lubricant that ensures the engine's performance. Based on this fact, in no case should you close your eyes to oil leakage, otherwise it will lead to blockages of the motor, to its failure and even to a fire.

Another dangerous consequence of oil leakage lies in the possible damage to the motor due to the lack or lack of lubrication during operation. In addition, the clutch may slip for the same reason.

It is often either difficult or impossible to solve such problems on your own, and then it will be safer to contact a car service.

How to find a leak

A visual sign warning of a leak is the appearance of a bluish haze from under the hood, as well as jerks on the oil indicator when the car is moving.

But in order to specifically identify oil leakage, you first need to measure its level... Do this with a special probe. It must be removed, wiped dry with a clean cloth to such an extent that you can see the mark. Then dip to the end and then remove.

This way you can determine the lubrication level. And, if it turns out to be less than the norm, then the oil should be added. And after adding, start monitoring its level every thirty minutes. If it falls very quickly, it means that the oil pan is damaged.

The next way to find the leak is using a fluorescent dye and ultraviolet light. To this end, dissolve the dye in the oil and pour the resulting mixture into the motor. Then start the car. Wait for the engine to idle for ten minutes, then turn off the engine and illuminate it with ultraviolet light.

You will find oil leakage in the place that will be highlighted most brightly. If the oil line is damaged, when the engine is started, oil will begin to flow due to the high pressure. In this case, the oil line must be replaced.

Another way is talcum powder... Sprinkle talcum powder on any leaks as abundantly as possible. After that, start the engine and fix idle speed on it for 10-15 minutes.

The meaning of this technique is that during the operation of the motor, the points of oil withdrawal will appear exactly where it is sprinkled with talcum powder. This is a fairly convenient and cheap method for detecting oil leaks. It is very important to find oil leaks in time and quickly fix this problem.

Reasons for the leak and how to solve the problem

It must be remembered that the problem is not where the oil goes to, but where it comes from. In most cases, the grease will go to the following locations:

stuffing box;
oil filter;
distributor;
valve cover;
oil pan gasket;
belt or chain pulley;
crankshaft seals.

The earlier the year of manufacture of the motor, the more likely a problem will arise from aging of the seal or gasket. Long-term use of these parts can lose flexibility or be physically damaged. Of course, then they will have to be replaced.

It is much more unpleasant if the cause of the lowering of the oil level through the oil seal is a worn out shaft. The fact is that sometimes from regular friction against the oil seal on the shaft a chipping occurs, through which the oil flows.

To eliminate this malfunction, it is necessary to replace the shaft, and this is a very expensive "pleasure". And the dismantling of the shaft itself is a rather laborious process, because you have to disassemble the entire engine.

The front oil seal wears out much faster than the rear oil seal. If you have to replace the crankshaft oil seals, then it will be useful to immediately change the camshaft oil seals.

The next possible reason for the leak is poor quality crankcase ventilation... The fact is that gases accumulate in the crankcase, due to which pressure arises. And the purpose of ventilation is to lower this pressure.

If the ventilation ducts become clogged, the pressure in the crankcase begins to displace the oil outward, and as a result, a leak forms. Therefore, before eliminating any leak, it is worth debugging proper ventilation.

Another reason for the leak is excessive wear of the piston group of the motor... With such a malfunction, leakage is inevitable even with perfect crankcase ventilation. It simply cannot handle the large amount of gases entering the crankcase, resulting in high pressure. For this reason, there is only one way out - replacing the piston.

If you notice oil streams coming from under the oil filter, you can fix the problem yourself. To do this, it is enough just to tighten the filter harder, and the oil will stop running.

If you find that grease is running out of the oil pan, remove the oil pan and inspect it. If the pallet is deformed, it is worth straightening, and then putting the pallet in place, sealing the connection points with sealant.

Leaks from the valve cover are eliminated as follows: the gasket must be removed, rinsed, and then, covered with sealant, put in place.

In addition, oil may begin to flow at the distributor anchorage points. In order to solve this problem, you will have to unscrew the mounting bolts, dismantle the distributor, then cover the joint with sealant and, at the end of the procedure, put the distributor in its rightful place.

In conclusion, we will say that in most cases the problem of oil loss in the engine can be solved independently. Of course, there are many such situations when it becomes necessary to send a car to a service station - and this needs to be done.
And most importantly, before each trip, inspect the car very carefully. This simple procedure will save you both time and money.

Any leaks of oil in the car can indicate a rather serious problem. So it will be much better and easier to perform a high-quality diagnosis immediately after you notice drops of oil in the garage on the floor or at a place of long-term parking. If an oil stain forms under the car, then the situation requires an immediate reaction. There are the most serious risks of losing expensive units due to their complete wear and tear. Operating with insufficient lubrication or no lubricating technical fluid at all can completely destroy many parts of your car. This is worth remembering in order not to become a victim of a very simple breakdown, which in the future can lead to very unpleasant consequences. It is difficult to imagine a transport that never in its life would require attention on this matter.

You can sometimes notice oil leaks in the engine compartment directly on the units. Technical fluids in a car are quite viscous, therefore, with a single hit on the surface, they perfectly spread over all parts and for a very long time are not washed off even by special means. Therefore, on the engine and gearbox housing, you can easily notice oil drips, which immediately turn black and collect dust. This is the main aspect of engine pollution. If any gasket or oil filler cap is loosely tightened, the lubricant will spill during operation. All this makes it quite easy to carry out a full inspection, even without specialists, in order to find out the basic possible problems. Let's take a look at the possible dripping of grease under the car.

Engine - Oil and Leakage Problems

There are literally dozens of options for the outflow of technical fluid from the engine crankcase. First, you should check the drain screw in the crankcase of your power unit. This part is of a fairly high quality in virtually all cars and has a very long service life. But many screws have rubber seals that fail over time. So it won't be superfluous to check this. Also, the reasons for oil leakage can be the following:

when refilling or replacing a lubricating technical fluid, a little oil was spilled, due to which the grease flowed down the engine for quite a long time and dripped down;
drops can form when checking the level of lubricant in the engine - not too viscous liquid from the dipstick may well fall to the floor, and then there will be a feeling of a breakdown in the car;
crankcase damage is another problem that often leads to significant leaks of technical fluid under the car, it is not always possible to determine visually;
a crack in the engine block leads to the fact that during operation the oil is literally squeezed out of the once sealed chambers, so that the entire unit turns out to be dirty;
there are other problems that require immediate solutions, an oil filter with a poor design or poor quality can leak, it is difficult to check.

During engine operation, the oil pressure in the system is quite high. So in case of any malfunction, the lubricant will find its way out and will drip. If it digs even without pressure, on a standing car in the garage, then you should pay special attention to possible malfunctions. After a certain time, you can simply be left without an engine. And in such a situation, you need to watch the oil level in the crankcase of the power unit as often as possible.

Gearbox is another source of dripping oil

It is possible that the drops of oil that you see under the car caused dripping from the gearbox. There is also a lubricant drain hole, which is worth checking first. But sometimes it drips in the most unexpected places. This is especially true for domestic gearboxes, the reliability of which is highly questionable. You can distinguish such a range of problems if you see oil drops under the box:

the bolt acting as a drain plug is damaged, the oil seal of this bolt deteriorated, which led to the active expelling of oil from the unit up to the last drops;
the cover has come off, through which oil is poured into the gearbox, and under pressure all the oil is driven out of the box, which is very dirty, and the remaining grease is actively dripping from it;
the anthers of the inner CV joint, which is included in the gearbox, are damaged, through which grease can actively drip in unlimited quantities onto the floor of your garage;
the box body is damaged by hitting an unevenness on the road, which led to a crack in the unit itself and oil discharged through a certain hole formed in this case;
it is possible to drive oil through broken axle shafts, which are bent or come out of the usual place of installation, in this case, the way for the oil to exit from the gearbox opens.

It is almost impossible to check all these situations at home. But you can just do good quality research at the workshop. To do this, you just need to give the task to the masters to see where the oil is dripping from. If you are sure that the problem is in the gearbox, you should immediately diagnose this unit, check the fluid level, and perform other maintenance tasks. This will often help stop smudges.

Does oil drip from under your car at all?

If you regularly find drops or even puddles of viscous oily liquid under your car, you need to first make sure that the problem is really with the oil. Perhaps this is just water that has accumulated during a trip, which washes away perennial dirt and flows down when the car is at a standstill. There are other options for the formation of unpleasant puddles during the operation and storage of the car. It is worth doing the following verification steps:

take a sheet of white paper, use a cotton swab to take liquid from a puddle and smear on the paper, look at the result and wait a few seconds to be sure;
if there is oil in front of you, the paper will take on greater transparency in the place where you smeared it with liquid, you will also see a greasy spot that does not go away for a long period of time;
if the stain is just wet, then you are dealing with a different liquid, it may be just water from the washer reservoir or rainwater collected in certain grooves;
if the paper starts to turn green, red or blue, it is worth checking the cooling system, most likely, it flows from there, and antifreeze is on the garage floor;
with a constant frequency of appearance of liquid on the floor in the place where the car is stored, you still need to carry out a full-fledged high-quality diagnosis and solve all problems.

Do not use the barbaric verification methods that are written about so much on the Internet today. Spare your car and take it to the master. You can simply show the car to an experienced person who knows more than you in technical aspects and can really help to complete all tasks efficiently and in a short time. All this will really help to find the problem and fix it in order to get rid of unpleasant and alarming smudges.

Diagnostics at service stations - what to pay special attention to?

It also happens that after long months of fighting leaks, the owner of the car goes to the service station. Here he is given an unrealistic bill for replacing some oil seal, he goes home happily, and the next morning he notices familiar spots on the garage floor that have not gone anywhere. Inspection at the station is best done together with the foreman, so as not to miss anything important. It is also worth giving certain conditions to a specialist:

fully tell where the liquid is oozing from, how it looks, how much it flows out - give all the information that you only have in your arsenal on the problem;
then ask to carefully inspect all the details that we talked about above, while many masters can persuade you, even without inspection, to simply change any part;
order diagnostics of the unit from which the liquid is flowing, this will help to understand the reasons for such an unpleasant effect, as well as eliminate the consequences of the leak as a whole;
order a full service for this unit so that the master refills oil if necessary or completely changes it, and also checks the levels of all technical fluids in your car;
in addition to these solutions, it is also worth checking the integrity of all anthers, which will help prevent grease mixed with water from leaking out (very similar to oil).

With this set of interesting features, you can just get to the point and fix the problem. Most likely, during the diagnostics process, a node will be found that needs to be serviced with high quality. You will be able to get maximum confidence with all the above processes without any problems. But for this you need to choose a professional station. Do not entrust the inspection and repair of the machine to unverified specialists - this can have a very bad effect on the serviceability of the transport. The problem can be traced to commonplace things, such as in the following video:

Summing up

We can talk for a long time about how exactly diagnostics and car repairs are performed. But it is better not to wait a second if you notice really dangerous symptoms with your transport. The best solution in this case would be to perform a high-quality inspection on your own right at the place where you first noticed an unpleasant moment. If you do not find a leak, you should immediately go to a specialist. In the absence of confidence in the safety of a particular problem, you better get help from specialists as quickly as possible.

Also, do not experiment in this situation. It is necessary to determine exactly where the oil is oozing from so that it can be easily removed. It is also worth warning of possible problems of the main units. To do this, you need to check the oil level in them constantly, use a variety of tools to obtain information about what exactly is wrong in your car. This will help you easily correct the situation and fix the problem. But it is not worth driving for a long time in a car from under which oil flows. Better to immediately go to the service station. Have you had situations when technical fluids flowed from under the car?

Also, strong oiling of the internal combustion engine can cause a fire. By the way, the specified layer of dirt and oil from the surfaces of the motor is removed with difficulty (you need a regular and full-fledged one, etc.).

Separately, it should be borne in mind that a leak can lead to the fact that. This will cause the motor to malfunction,. Also, grease can damage the insulation of the wires under the hood, get on the clutch, soften rubber pads, seals, interact with plastic parts, etc.

Why is the engine in oil: possible causes

It becomes clear that for the normal operation of the internal combustion engine, it is necessary to eliminate the causes of oil leakage in the engine as soon as possible. At the same time, experts identify several reasons for this.

Immediately, we note that it is far from always possible to quickly find the place of a leak. Many parts and elements make it difficult to access for inspection, and the space in the engine compartment on many cars is very limited.

This means that if the engine is in oil, drops of fresh lubricant are visible under the car after parking, then it is highly desirable to drive the car into an inspection pit, lift it on a lift or drive onto an overpass. This approach will make it possible to inspect the engine from both above and below. By the way, if there is an engine protection, this element will need to be removed.

So, the main reasons for oil leaks are as follows:

increasing the oil level in the engine (overflow);
using the wrong type of lubricant;
crankcase ventilation problems;
oil leak from under the valve cover;
oil leak in the distributor area;
oil flows from under the oil filter;
the oil pan is punctured or cracked;
the front / rear crankshaft oil seal is leaking;

Quite often, car owners who themselves change the oil in the engine accidentally (sometimes deliberately) exceed the lubrication level. The result is increased pressure in the lubrication system, the excess oil is simply squeezed out through the gaskets and seals (especially on old motors). In this case, the excess oil must be pumped out of the engine.

Also, oil can leak if the engine is filled with too "liquid" or counterfeit lubricant (the SAE viscosity is not suitable, the properties of the oil do not correspond to the declared ones). In such a situation, the grease must be drained, after which the engine is washed and a proven, high-quality product suitable for tolerances and recommendations is poured.

It may also be necessary to make an additional correction for individual operating conditions (constant operation of the motor under heavy loads at high speeds, intense heat in the region, etc.).

We add that certain malfunctions also lead to the fact that an increase in the level of lubrication occurs. Such breakdowns should be attributed. In this case, the lubricant loses its useful properties and liquefies, an emulsion is formed. Often in this case, oil leaks through the engine seals as well.

The crankcase actually acts as an oil reservoir on many vehicles (except dry sump systems). As the piston rings wear and out of the combustion chamber, some of the exhaust gases erupt into the boat. This leads to an increase in pressure.

This overpressure must be compensated for. If the system does not work or does not work correctly, the exhaust gases "squeeze" the oil out of the crankcase. Often, the driver can find that the entire engine is in oil, while squeezing out the oil dipstick.

The valve cover most often leaks due to the destruction of the valve cover gasket, as well as as a result of deformation or damage to the cover itself.

Depending on the problem, it is necessary. Also, the lid can be placed on a special sealant.

On domestic cars, one of the most common places for oil leaks is the distributor. If oil flows from under the distributor, the problem in some cases can be solved quite simply.

To do this, remove the cover from the distributor, then the device itself is removed. Next, a sealant must be applied at the junction, after which the assembly is carried out in the reverse order.

On many cars. The reason may be incorrect tightening of the filter without a special wrench (the filter is under-twisted or twisted).

In the first case, the filter must be tightened, in the second case, the rubber O-ring is deformed, as a result of which it is necessary to purchase another oil filter. Also, product defects should not be ruled out, especially when it comes to the cheapest filters. Less often it happens that the matter is not in the filter itself, but in the threaded seat. If a breakdown occurs in this area, repair is required.

Cracks and damage to the oil pan occur quite often, especially taking into account the operation of a car on domestic roads without installing additional engine protection.

As a rule, such a breakdown leads to intense leaks. In this case, it is necessary (to weld the pallet).

Repair operations are carried out only after dismantling the pallet. It is quite obvious that the installation of a crankcase protection, although it does not completely exclude, however, significantly reduces the risks of such malfunctions.

Quite often, drivers are faced with such a nuisance when. The power unit has two crankshaft oil seals (front oil seal PSKV and rear oil seal ZSKV).

As a rule, oil seals flow on motors with a range of 100 thousand km or more. and more. A sure sign of problems with oil seals on many cars is oiling in the timing belt installation area (front oil seal), as well as oil leakage in the area of the gearbox and engine interface (oil flows between the engine and the gearbox), oil stains are visible under the car after parking (rear oil seal ).

Such a breakdown is serious and requires specialist intervention. It is not recommended to drive the car before the repair. For example, if the front oil seal is leaking, oil can get on with all the ensuing consequences (belt slippage, breakage, etc.). Leaks in the area of the rear oil seal can cause grease to enter the clutch components. To replace the ZSKV, it is necessary to remove the gearbox.

How to find the location of an engine oil leak: available methods

As already mentioned, to find the leak, the engine must be inspected from all sides. First of all, check the engine oil level. If the level is increased, we find out the reason, if it is lowered, we bring it back to normal.

Often, a strong leak will be indicated by a drop in the oil level in a short time. In such a situation, you should pay attention to the condition of the oil pan. It is possible that repair or replacement will be required.

If we talk about gaskets and seals, strong leaks through them are also possible, but they are less common. But the oil can gradually flow out, leaving drops under the car or drips on the internal combustion engine.

If you cannot see where the grease is coming from, talcum powder can be sprinkled on potential problem areas to pinpoint the source. The method is simple and convenient, well suited for garage conditions. Next, the motor must be started for 10 minutes. in idle mode or drive a car for 2-3 km. Then you need to inspect the previously covered with talcum powder, revealing fresh oil on a white powder.

Finally, we note that many service stations practice the addition of a special dye to the oil. Such a dye is a fluorescent. Then the engine is started, after which it is allowed to work on the XX or it is proposed to drive 3-5 km. Then, using a fluorescent lamp, the internal combustion engine is carefully examined, determining the areas where the oil containing the pigment glows.

Breakdown diagnostics

Experienced motorists always inspect the garage floor or asphalt for such puddles before getting behind the wheel. If the search was successful, do not delay the technical inspection. However, in some cases, you can fix the problem yourself. How to assess the situation and how to proceed will be discussed in this article.

No one will be delighted with a viscous black puddle under their car. This is a clear sign that something is wrong. How to be? Should I go to the service station right away, or can the trip be delayed? We do not recommend delaying if you find a leak outside of a garage. If you have the time and desire to tinker with the car, then here's where to start.

First of all, if you find a drip on the floor, pay attention to the liquid itself. It may be dark brown and viscous - this is an engine leak. The transmission fluid has a pinkish or red tint, while the green or orange fluid is most likely antifreeze. Another sign of a leaking engine is the appearance of bluish smoke from under the hood.

But how do you root out the problem in the bud? This way you can avoid a lot of further complications. If oil leaks from the engine, it is fraught with damage to it or even a fire in the car. So where to start diagnostics? First, you need to find out the oil level with a dipstick. Lower the dipstick and compare the fluid level with the normal level, then add oil. Check the level every 30 minutes to find out the leak rate. This will help determine where exactly it comes from. For example, if the level drops quickly, the oil pan is most likely damaged.

A more technologically sophisticated way of tracking is adding a fluorescent dye to the oil. The engine should then run for ten minutes. After the plug, it will become clear where the oil may come from - under ultraviolet light, the leaks will glow brightest.

Another source of problems can be the oil line, which will start to flow when fluid is added. The way out is to replace the oil pipeline.

Why does engine oil leak?

When the fluid starts to leak, it is best to contact a service center. But before that, you can provide first aid to the car and determine a lot of points that will save time for the workshop workers and money for you.

So, what is the reason for such breakdowns and how to avoid them? Typically, the most leaking locations are:

Crankshaft oil seals;
Oil pan of the engine and gearbox;
Oil filter;
Place of fastening of the distributor;
Valve lid.

Engine age is a significant factor in leakage propensity. The longer the motor runs, the greater the damage to its parts, in particular the gasket and seal. Replacing them is the perfect solution.

It is much more difficult to eliminate the leakage due to shaft wear. The cause of the smudges is the groove made by the shaft in the oil seal. In this case, it will be necessary to change the entire shaft, and for this to disassemble the engine.

ADVICE! Oil seals, as a rule, wear out unevenly - the front is more intense than the rear. Therefore, it is better not to skimp and, if one of them is worn out, replace both during repairs.

Also, oil can leak due to poor crankcase ventilation. The task of the ventilation system is to free the crankcase from accumulated gases, relieve pressure. But over time, the system clogs up and pressure builds up in the crankcase. This is what pushes the oil out of the engine. Eliminating ventilation blockages is a mandatory procedure when repairing a leak.

A common cause of leaks is worn out engine pistons. In this case, even the ventilation system will not help.

The situation with the oil filter is simple - either tighten it or replace it.

Oil also frequently leaks out of the sump. To repair, you need to check the pallet for distortions, then fix them and seal the pallet. In addition, the valve cover can be a source of leakage. It should be cleaned, lubricated with sealant and reinstalled. To fix leaks in the place where the distributor is attached, unscrew the distributor, and coat the joints with sealant.

In order to protect the motor from damage, we advise you to install a crankcase protection - this will help to avoid such causes of leakage as penetration or deformation.

In general, this is the whole technique for repairing leaks. If the problem lies elsewhere, you can solve it either by replacing, or sealing, or simply tightening the fasteners.

The last, but not least, factor in the formation of leaks is the quality of the operating fluid. In some cases, it is useless and leads to breakdowns. Use modern oils from leading manufacturers, they are formulated for economical consumption and minimum evaporation.

Nevertheless, the situation with lubricating fluid cannot be called deplorable, because in conditions of healthy competition, manufacturers do not hack, and drivers choose the best option wisely.

How to prevent oil leakage?

In conclusion, I would like to say that regular engine diagnostics is one of the keys to its serviceability and durability. In addition to checking, one should not forget about practice - that is, winter-spring prevention.

Thanks to the lubricating fluid, the car will be able to maintain its performance as long as possible. Leaks are guaranteed to reduce both the durability of the vehicle and its comfort. In addition, such a problem can be called money down the drain, because oil is simply spent in emptiness.

The best proof of love for the car will be the replacement of all unstable, obsolete or wear parts of the engine.

You can even outline the following list so you don't forget:

Oil pan;
Oil seals (it is difficult and not necessary to change, but it is the law to check);
Valve cover gasket (replacement or sealing);
Gasket of the pallet and the upper cover of the gearbox;
Gasket between exhaust manifold and exhaust pipe.

After replacing and diagnosing all these elements, mark the event with the addition of new oil, and the machine will thank you with good work.

If you cannot find the time to complete all these procedures, then do not forget to insist on checking the details at the service station. The specialists will cope with their task and you will only have to enjoy the confident road. Enjoy your safe ride!
