Camshaft oil seal: replacement and selection

When and why it is necessary to replace camshaft oil seal

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.

There is a risk to make an error during demounting and installation of the parts if you have no special skills.

Often, a valve cover gasket is installed together with the camshaft oil seal. Moreover, if oil got onto the timing belt because of the defective component, it is recommended to replace it in a kit with the rollers.
