Checking the pressure loss in the engine (1,8 l

Apply a layer of silicone sealant (gray) with a thickness of about 2 mm (the size I) in place of the body synchronization and the cylinder head.

NOTICE Visually check the bolts and make sure the seal is not damaged. If necessary, replace the bolts with new ones.

Tighten the mounting bolts 13 point 8 Nm Replace ignition module. Connect the module to the spark plugs. Tighten the two screws fastening point 8 Nm Install the ignition module cover on the lid of the cylinder head. Connect the wiring harness ignition module. Attach the wiring harness on the lid of the cylinder head. Connect the camshaft sensor, mass airflow sensor, pressure sensor oil and coolant temperature sensor. Replace the air filter housing on the arch of the wheel and tighten the attachment bolt. Attach the intake hose to throttle module and attach the clamp. Attach the hose to the ventilation of the engine air intake hose and secure clamp. Connect the wiring harness to the sensor air flow mass. Connect the ventilation pipe of the fuel tank. Close the hood.

Removing the air filter housing

Open the hood.

NOTE Before the verification procedure warming up the engine to operating temperature (oil temperature - 80 ° C).

Loosen nuts and remove the massive wire from the battery. Remove the air filter housing and intake manifold.

Connect the tester to the system pressure drop, the compressed air (Figure 2.50). Calibrate the tester pressure drop. Turn prvuyu transfer and parking brake systems.

NOTE The wheels must be in contact with the ground.

Replace the connection piece into the threaded hole plugs cylinder number 1. File a compressed air into the cylinder.

Check the pressure drop

Determine the value of pressure drop. The maximum allowable pressure difference between the cylinders - approximately 10%. Maximum loss of pressure in the cylinder - 25%.

NOTE Watch for any visible leaks of compressed air in the intake and exhaust manifold and the crankcase. Pay attention to the bubbles in the coolant expansion tank.

Rotate the crankshaft 180 ° in the direction of motor rotation (corresponding to 90 ° rotation of cam gear) and set the piston cylinder number 3 in the position of top dead center (TDC) (pre-stamped label). Connect the tester pressure drop. Replace the connection piece into the threaded hole plugs cylinder number 3 and submit the compressed air into the cylinder. Determine the value of pressure drop. The maximum allowable pressure difference between the cylinders - approximately 10%. Maximum loss of pressure in the cylinder - 25%. Rotate the crankshaft 180 ° in the direction of motor rotation (corresponding to 90 ° rotation of cam gear) and set the piston cylinder number 4 in the position of top dead center (TDC) (pre-stamped label) Connect the tester pressure drop. Replace the connection piece into the threaded hole plugs cylinder number 4, and submit the compressed air into the cylinder. Determine the value of pressure drop. The maximum allowable pressure difference between the cylinders - approximately 10%. Maximum loss of pressure in the cylinder - 25%. Rotate the crankshaft 180 ° in the direction of motor rotation (corresponding to 90 ° rotation of cam gear) and set the piston cylinder number 2 in the position of top dead center (TDC) (pre-stamped label) Connect the tester pressure drop. Replace the connection piece into the threaded hole plugs cylinder number 2 and submit the compressed air into the cylinder. Determine the value of pressure drop. The maximum allowable pressure difference between the cylinders - approximately 10%. Maximum loss of pressure in the cylinder - 25%. 159
