General information on settings

The term "control" in this manual is meant as rather not one separately taken procedure, but 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 given above, checks of a state to subject increased wear of components 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 work will be minimized.

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

The first step at implementation of adjusting and diagnostic procedures is measurement of compression pressure in cylinders. Measurement of compression pressure (see the Head the V8 Engine) allows to define the general condition of internal components of the engine and its results have to be considered as basic data when holding procedures of control and restoration of the engine. For example, if results of measurement of compression 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 in overall performance of the engine and will be only waste of time and means. In view of importance of value of this check, measurement of compression pressure has to be entrusted to the mechanic having the corresponding experience and having the necessary equipment.

It is possible to call the listed below procedures the main of necessary for reduction in satisfactory condition of not well-groomed engine.
