Camshaft Chain Tensioner Upgrade Kit for the Left Hand Side - includes Piston, Piston Cylinder, Spring (Pre-installed) and Washer.

The right hand side tensioner is always immersed in oil and does not need to be replaced, however we do carry this part - see: CamTensioner331

The original left hand tensioner has a very weak spring and has no check valve so it loses hydraulic pressure when you turn the engine off. The upgrade is identified by the smaller 15mm head (the normal tensioner is 17mm) and has an internal check valve that retains oil and appropriate pressure.

NOTE:: This tensioner is for earlier models, see CamTensioner797 for later models.
