Dear V8 owner,
If the timing chain is allowed to slap the chain rails and guides the impact will break the nylon into little pieces. The pieces lodge between the chain and sprockets. You know the story. Does the engine make rattling noises when started cold? If it is'nt started for many days the tensioner bleeds down and allows the chain to whap the nylon when cranked. Carefull now my friend.
