This chapter describes the checks and adjustments necessary to maintain high vehicle performance, economy, driving safety and durability.
If the maintenance procedure has not been followed for a long time, the following checks and adjustments should be performed more frequently or as needed. The largest amount of adjustment and adjustment work is usually performed on the engine. This is especially true for the engine of a used car that has not been subjected to regular or timely inspections. In such cases, in addition to periodic maintenance, additional adjustment work must be performed.
If there is a suspicion of engine wear, it is necessary to check the compression in the cylinders and obtain valuable information regarding the condition of all the main parts of the internal structure of the engine. Based on this information, you can get an idea of the scope and degree of complexity of the upcoming work. If, for example, the compression is such that it clearly indicates severe engine wear, then current maintenance will not restore normal performance and a major overhaul with complete disassembly should be performed. Below is a list of works that most often need to be performed to improve persistent abnormal engine operation.
