How to replace valve stem seals?

Average lifetime limit of valve stem seals is 150 000  - 200 000 operational kilometers and depends on the quality of motor oil used. The part is not subject to repair, when worn out it is replaced. Selecting valve stem seals take into account manufacturer’s recommendations. The case is that the size of installed components will vary for every car engine model. Moreover, the quantity of components should coincide with that of valves.

Replacement of these components is performed by service station specialists because demounting of valve stem seals is performed using a special tool. The replacement procedure on cars of different models often has specific features due to complexity of access to damaged components. For example, usually ignition coils and plugs have to be removed, then the valve cover and then the camshaft. Sometimes replacement of stem seals is impossible to perform without demounting the cylinder head. It is recommended to install a new valve cover gasket kit together with valve seals on the car.
