Mass air flow sensor – thermopneumatic flow meter IVKSH 407282000, installed in the intake system after the air filter.
The sensor determines the amount of air entering the cylinders during engine operation.
In the fuel injection engine power system, the pressure is 30 MPa (3 kgf/cm 2)
Over time, during operation, the gasket under the engine head cover loses its elasticity and strength and oil leaks from under the cover
An external sign of wear on the valve stem seals is the short-term appearance of blue smoke from the exhaust pipe after starting the engine, as well as when braking the engine after prolonged driving under load
A sign that the front crankshaft oil seal needs to be replaced is oil leaking through its lip
If an oil leak through the oil pan gasket cannot be eliminated by tightening its mounting bolts, it means that the gasket is severely deformed and must be replaced
If the seal of the gasket is broken, exhaust gases break out, accompanied by a characteristic sound (the collector “slashes”)
