Camshaft oil seal: replacement and selection

When and why it is necessary to replace camshaft oil seal

Lifetime limit of this component is averagely 100 000 – 120 000 kilometers of mileage. A new oil seal is required if the old one stopped providing unit hermeticity. Particularly, the part can dry out, cracks can appear on it. Moreover, its thermal damaging is possible.

Constant friction between the shaft and the oil seal promotes its wear, as well as influence of high temperature in case of engine overheating. This can occur, for example, because of cooling system elements defectiveness. In addition, the component dries out if the car is not in operation for long.

Poor condition of the oil seal can be indicated by excessive oil consumption. Level of this working fluid is checked with the help of a dipstick. The indirect sign of camshaft oil seal depressurization is engine efficiency worsening. This occurs because oil gets onto the timing belt because of the worn out component. In this case, it stops properly operating, which leads to lowering engine power.

You should apply to a service station in order to replace the oil seal. This is determined by necessity of car de-energizing, demounting of auxiliary equipment and the timing mechanism belt for this procedure.
