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

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)
