2.6.3. Check of loss of pressure in the engine (the engine of 1,8 l)

Removal of the case of the air filter
Open a cowl.

The components removed at dismantle of the air filter: 1 – fastening bolt; 2 – inlet collector; 3 – socket of a plait of wires of the sensor of a mass consumption of air; 4 – case of the air filter

NOTE
Before the procedure of check warm up the engine up to the working temperature (oil temperature – 80 °C).

Turn off a nut of fastening and disconnect a mass wire from the rechargeable battery.
Remove the case of the air filter and an inlet collector.
Disconnect the socket of a plait of wires of the sensor of a mass consumption of air.
Turn off a fastening bolt, remove a collar and an inlet pipe of the air filter.

Removal of a forward cover of a gear belt
Turn off two bolts of fastening, disconnect the top latch and remove a forward cover of a gear belt (top).

Fastening of a forward cover of a gear belt: 1 – forward cover of a gear belt; 2 – fastening bolts; 3 – latches

NOTE
Extend a forward cover of a gear belt up, for a ledge (the shooter in the drawing).

Uncover the ignition module in the direction of the arrow represented on it.

Removal of a cover of the module of ignition: 1 – fastening bolts

NOTE
Note the provision of an arrow on a cover.

Having turned off 2 bolts, remove spark plugs, using the KM special tool 6009.
Uncover a broad tank of cooling liquid.
Take out the oil probe.
Lift the car.

Removal of the right boryzgovik of the engine
Turn off 4 bolts of fastening and remove the right mudguard of the engine.
Remove two rivets established on a body.

Components, heads of the block of cylinders uncovered at dismantle: 1 – right mudguard of the engine; 2 – fastening bolts; 3 – rivets

Installation of a bent shaft in the provision of the top dead point (TDP) of the piston of the cylinder No. 1
Turning a bent shaft of the engine in the direction of rotation, install the piston of the cylinder No. 1 in the provision of the top dead point (TDP) (a tag 1).
Lower the car.

Installation of a bent shaft in the provision of the top dead point (TDP) of the piston of the cylinder No. 1: 1 – tags

Apply 3 tags on one of cogwheels of a cam-shaft and combine tags on both wheels.

Combination of tags on cogwheels of cam-shafts: 1 – tags

Each tag has to be displaced on 90 ° rather next tag.
Connect a pressure drop tester to system of supply of compressed air.
Calibrate a pressure drop tester.
Include prvy transfer and the parking brake system.

NOTE
Wheels have to be in contact with the earth.

Screw a connecting detail in a carving opening of a spark plug of the cylinder No. 1.
Give compressed air to the cylinder.
Pressure drop check
Define value of pressure drop.
The maximum admissible pressure difference between cylinders – about 10%.
The maximum loss of pressure in the cylinder – 25%.

NOTE
You monitor any visible leak of compressed air in inlet and final collectors and a case.
Pay attention to bubbles in a broad tank of cooling liquid.

Turn a bent shaft on 180 ° in the direction of rotation of the engine (corresponds 90 ° turn of a cogwheel of a cam-shaft) and install the piston of the cylinder No. 3 in the provision of the top dead point (TDP) (previously put tag).
Connect a pressure drop tester.
Screw a connecting detail in a carving opening of a spark plug of the cylinder No. 3 and give compressed air to the cylinder.
Define value of pressure drop.
The maximum admissible pressure difference between cylinders – about 10%.
The maximum loss of pressure in the cylinder – 25%.
Turn a bent shaft on 180 ° in the direction of rotation of the engine (corresponds 90 ° turn of a cogwheel of a cam-shaft) and install the piston of the cylinder No. 4 in the provision of the top dead point (TDP) (previously put tag)
Connect a pressure drop tester.
Screw a connecting detail in a carving opening of a spark plug of the cylinder No. 4 and give compressed air to the cylinder.
Define value of pressure drop.
The maximum admissible pressure difference between cylinders – about 10%.
The maximum loss of pressure in the cylinder – 25%.
Turn a bent shaft on 180 ° in the direction of rotation of the engine (corresponds 90 ° turn of a cogwheel of a cam-shaft) and install the piston of the cylinder No. 2 in the provision of the top dead point (TDP) (previously put tag)
Connect a pressure drop tester.
Screw a connecting detail in a carving opening of a spark plug of the cylinder No. 2 and give compressed air to the cylinder.
Define value of pressure drop.
The maximum admissible pressure difference between cylinders – about 10%.
The maximum loss of pressure in the cylinder – 25%.

Installation of components
Lift the car.
Establish an engine mudguard.
