This section included the general methods of dismantling of a head of the block of cylinders and other knots of the engine.
Information concerns sequence of preparation for repair and the step-by-step description of operations of removal and installation of components of the engine and their check.
It is not always easy to define as where in the engine demands repair: too many factors should be taken into account. Big run of the engine is not always the prerequisite to repair and vice versa, small run does not guarantee lack of need under repair.
The raised consumption of oil testifies to need to pay attention to a condition of piston rings, maslosjy ny caps and the directing valves. At making decision on repair of the specified knots certify in lack of a leak of oil. Measurement of a compression in engine cylinders can give additional information on volumes of repair.
Check oil pressure size by means of the manometer installed instead of the oil pressure sensor. The lowered size of pressure of oil testifies to wear of bearings or damage of the oil pump.
Falling of power, uneven operation of the engine, blows and mechanical noise, the increased noise of the valvate mechanism and high fuel consumption, as a rule, testifies to need of repair, especially, if all these troubles arose at the same time.
