Not again!! Cam Chain Tensioner Spring

[nick crisp]

Have you tried holding the tensioner blade against the chain with your finger through the tensioner hole whilst manually turning the motor? If you have any tight spots on the cam  chain the blade will move back and forth excessively which might explain two broken springs. The manual tensioner could be exerting a lot of stress on the valve train components if this is the case.

:eek  Just when you thought it was safe to fit a manual tensioner.... :rollin
