There are simple ways to determine that the car VAZ-2107 engine power is lost. They are as follows:

1. Too much engine oil consumption.
2. Reduced acceleration of the machine during normal operation of the carburetor.
3. The presence of exhaust gases of dirty color and soot.
4. A large number of traces of soot.

What are the reasons for the reduction in the power of the power unit?

• Violation of the fit of the pistons to the walls of the cylinder;
• Loss of compression.

Malfunctions such as reduced compression, worn piston rings, and a change in the diameter of the cylinder operating rings to maximum can be the reason for major repairs. Those who decided to save and the car VAZ-2107 engine to repair their own hands, the recommendations listed below.

Recommendations for the repair of the engine "Seven":

• It is necessary to prepare a place for repair work on the engine. To do this, you need a pit and a crane-beam, since the engine will have to be removed in some way. Otherwise, repairs will be doomed to failure.
• To release access to the engine compartment, remove the bonnet.
• Disconnect the battery and remove the battery.
• Work on opening the radiator and expansion tank by unscrewing all the necessary bolts.
• The antifreeze.
• Draining the engine oil from the crankcase.
• Removal of the air filter and carburettor. These parts must be put aside, as they will not be needed for a long time.
• Disconnect from the gasoline pump dangling hose. To minimize the loss of gasoline, you need to insert a bolt M8 into the lumen.
• Removal of the power unit.
• Disconnect the nipples leading to the stove, the coil wires and the spark plug.

Internal work in the engine

• Shooting of the camshaft and timing star.
• Unscrew the heads of the cylinder block, for which you need to stock up the torque wrench.

This is one of the important procedures, and it is necessary to start it if there is practice in this matter. In the absence of experience, read the detailed instructions for working with these screws and keys.

• Disconnect the exhaust manifold and complete the removal of the cylinder head.
• A careful inspection of the pistons and cylinders on the issue of the embossed notations.
• It's time to get into the pit to remove the protection of the crankcase.
• De-energize the generator and remove it together with the belt.
• Full removal from the car starter.
• Removal of all pipes from the cooling system, radiator and water pump.

Prepare to ensure that your garage will resemble flea market. Next, you have to remove all the clutch housing anchors, the nuts from the engine cushions and use the help of a partner to suspend the engine on the beam.

Then you need to take the following steps:

1. Removal of the oil filter, coupling, a flywheel, a chain ГРМ, a star коленвала.
2. Inspection of the crankshaft.
3. Transition to work with the block of cylinders.

If you are not afraid of these works, you can proceed with the overhaul of the car VAZ-2107.

Engine and workshop

It should be noted that without the help of STO can not do, because they will have to turn to them for services of boring the cylinder block and grinding the crankshaft. Also, it may be necessary to perform other works. The car VAZ-2107 engine repair carry out the checked up auto repair shops with the certain machine tools and the qualified experts.

When carrying out repairs yourself it is necessary to know the list of basic malfunctions that can occur with the VAZ-2107 engine.

VAZ-2107 engine - faults

1. Problems with the operation of the power system, up to the complete failure of the fuel pump and both pipelines.

2. The presence of debris in the fuel and air jets.

3. Impaired action of the membranes of the trigger device associated with their damage.

4. Problems with serviceability of high-voltage wires, candles and a distributor up to their complete failure.

5. Failure of the pump, the presence of debris in the filter.

6. Maximum wear on the cylinder with the piston, camshaft, timing.

Injector engine VAZ-2107 also has a number of malfunctions, which can be eliminated by hand.

Motor malfunctions

A clean unit is not only an indicator of the motorist's love for his vehicle, but also a major factor in increasing his capacity and efficiency. It contributes to a better return of the car, saving fuel. The problems of the VAZ-2107 engine (injector), associated with pollution, contribute to reducing the volume of injected fuel and disrupting the composition of the air-fuel mixture.

To "cure" the contamination of injectors can electronic systems. But this treatment is not the main one, since the problem remains on the VAZ-2107. The engine (the photo is shown below) ceases to pull normally, the flow rate increases, etc.

The main signs of clogging are:

• Uneven motor operation;
• Intermittent ignition;
• Loss of capacity;
• Engine failure or failure.

If one of these signs is confirmed, immediately repair the VAZ-2107 engine. Ignoring this requirement will lead to irreparable damage.

Carrying out repairs can be either independent or with the involvement of specialists.

Some experts believe that the following steps must be taken to correct the situation:

- after complete cleaning of the injector, unscrew, properly clean or change the spark plugs.

The explanation for this action is quite simple: the presence of a large amount of soot, which settles on the spark plugs and slows down their work.

Also, you can change the oil and filters, since getting a solvent in the oil leads to a decrease in its quality. One way or another, the important thing is to monitor the technical condition of your car and timely troubleshooting on the car VAZ-2107.

Carburettors are much less often injected. This is due to the fact that the VAZ-2107 injection engine is equipped with electronic control systems. And many motorists, having such an opportunity, have replaced the old motor with a new one.

Secondary market

Many drivers prefer to save and buy a used engine, which is priced in the range of 20 to 2 thousand rubles. With a mileage of not more than 50 thousand km.
