The exhaust manifold - a node that is responsible for the quality of the ride, without which the comfort is impossible. This is silence and lack of smell of exhaust under the hood, which can tighten into the salon through the opening of the cabin filter. Eliminating the leakage of the exhaust collector VAZ 2114 - Repair required. Fortunately, it does not happen urgent, you can prepare in advance and choose a convenient moment.
Graduation collector on VAZ 2114
The key factor that is the cause of 90% of the output manifold malfunctions on VAZ 2114 cars is a high temperature and not the highest-quality materials from which the parts are manufactured. In the process of operation, steel heats up repeatedly and cools, which leads to the appearance of cracks on the case. This is a frequency phenomenon for VAZ cars older than 7-8 years.
Car services offer cowing services with argon welding. However, for a number of reasons for a car older than 7 years, this occupation is useless.
1) Just remove and put the exhaust manifold will cost about 2.5 thousand rubles. Taking into account the work of the welder and other actions, the cost of repair can be 4-5 thousand rubles. If you do work yourself, buying a new detail will cost cheaper.
2) Welding, even argon, violates the structure of the "tired" metal. Boiled item rarely serves longer than a year, after which new holes appear. The older the car is the faster the problem returns, and the collector has to be removed again.
If a car over 8 years old and there are problems with cracks in the collector, it is better to remove the item and change to the new one.
Signs of faults
Laying the exhaust manifold
One of the main signs of leshes in the system is a "sports" lever when the engine is rotated. This may be a symptom of different failure of the exhaust system. To check it is better to take the assistant and go to the garage with the pit or on the flight. Most often, the eye can be determined, the problem in the silencer, a resonator or release.
Gasket wear can manifest itself during the factory. Open the hood and boot the car - white or grayish smoke, rising from the header during the warm-up, indicates a leakage for this reason. With this problem, the owners of VAZ cars usually face once every 3-4 years. When using low-quality spare parts before. The output can be the manufacture of steel laying to order. It can serve as much as the collector entirely.
Service experts, attracting customers, love to tell the terrible stories about the explosion of the exhaust manifold on VAZ 2114 cars due to cracks. In fact, it is nothing more than a myth. But the real problems are no less serious, so it is not worth postpone the repair in a distant box.
Cracks in the graduate manifold or worn gasket may cause dirty engine operation.
1) A lambda-probe has been installed in the exhaust manifold that affects the operation of the injection system. The strong air seats violates the mass content of oxygen in the exhaust, the lambda incorrectly adjusts the quality of the mixture, causing a rode, uneven idle, power loss, "black" candles.
2) Another feature is the crankcase ventilation. Disturbation of air circulation causes violations in the operation of the gas distribution mechanism, increased wear of the valves, the formation of nagar on the pistons and other "joys".
If the increased noise and unpleasant odors during the operation of the motor are combined with dirty work, the car needs urgent repairs.
Tool and necessary parts
To remove the release manifold on the VAZ 2114 in order to replace the gasket or part of the whole, the following tool will be required:
- keys horn and cape for 8, 10, 13, 17;
- head key at 17, 19;
- screwdrivers, Passatia.
It is also desirable to have such instruments such as dremel, hypooresis or a gyclub. As a rule, fasteners on the details of the exhaust system accumulates tightly.
A few days before the planned repair, start processing the available WD-40 nuts or another penetrating lubricant. Repeat the operation 2-3 times. This will slightly simplify the task of removing the collector .
The question often arises: whether after the removal and replacement of the gasket use the sealant. Experts believe that if we smear the gasket with a sealant - then only high-quality silicone. A bad sealant is able to bring the engine VAZ 2114 a lot of troubles: Going, it turns into "katoshka", which tightens into the crankcase. And this is unnecessary pollution of the piston system.
The procedure for removing the exhaust manifold
Before removing the exhaust collector yourself, think 7 times. The fulfillment of this work in the service is expensive, but the inaccessibility and complexity of unscrewing some nuts can be a serious problem.
Turn the fastening bolt to the inlet tube
Before removal, it is important to drain the cooling fluid, since the antifreeze process can get into cylinders. The sequence of actions for cars with an injector is as follows:
- Disconnect the battery, release the gas cable from the throttle.
- Disconnect the tubes of fuel highways.
- Disconnect the wires from the DPDZ and the idle regulator.
- Release hoses of crankcase ventilation, vacuum, brake amplifier.
- Remove the receiver, remove the nozzle block wires and remove the injector fuel ramp.
- Remove bracket and thermoeker.
- After that, you can disconnect the receiving pipe, graduation and intake manifold from the collector.
All gaskets after parsing change new ones. Pay attention to the purchase that the gaskets of the exhaust manifold for 8-valve and 16-valve VAZ 2114 are different. Pick the details carefully, and you can avoid loss of time and money.
