Intensive service

If the maintenance procedure has not been followed for a long time, then the checks and adjustments described below should be carried out more often, or as needed. The greatest amount of adjustment and adjustment work, as a rule, is performed on the engine. This is especially true of a used car engine that has not been subjected to regular or timely checks. In such cases, in addition to periodic maintenance, it is necessary to carry out additional adjustment work. If there is a suspicion of engine wear, then it is necessary to check the compression in the cylinders and obtain valuable information regarding the condition of all the main parts of the engine's internal structure. 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 routine maintenance will not restore normal performance and an overhaul with complete disassembly should be performed. The following is a list of work that is most often required to improve persistent abnormal engine operation.
