Repair and car operation

General information on settings

The term "control" in this Management is meant rather not as one separately taken procedure, and the whole complex of adjustments and installations.

If from the moment of acquisition of the new car all procedures of routine maintenance were made honestly and according to the schedule provided above, checks of a condition of components subject to raised wear and levels of liquids were rather often made, the engine of your car with the maximum degree of probability will reliably serve during long term and need of carrying out additional repair and recovery operations will be minimized.

On the other hand, the unfair relation to care of a vehicle most likely will lead to fast decrease in overall performance of the engine. Especially characteristic such situation is for a case of acquisition of the second-hand car when his previous owner did not give to care of the vehicle of due consideration. In that case first of all it is necessary to make unplanned complete setup of the engine.

The first step at performance of adjusting and diagnostic procedures is measurement of kompressionny pressure in cylinders. Measurement of kompressionny pressure (see. Head the V8) Engine allows to define the general condition of internal components of the engine and its results should be considered as basic data at carrying out procedures of control and engine restoration. For example, if results of measurement of kompressionny pressure in cylinders allow to assume considerable internal wear of the engine, carrying out even a full complex of settings and adjustments will not give desirable increase of overall performance of the engine and is only waste of time and means. In view of importance of value of this check, measurement of kompressionny pressure should be entrusted to the mechanic having the corresponding experience and having the necessary equipment.

Listed below procedure it is possible to call main of necessary for reduction in a satisfactory condition of not well-groomed engine.
