neilireland. You said the tensioners were ok normally, if so how is the chain jumping?
Either the tensioner must be going slack until filled with oil or there just isn't enough interference between the chain and cam sprocket.
Noticed. His has only done 57k as well. I wonder what mileage this one has done.
There has to be either a design fault or duff tensioners causing this.
The mileage i have done them from is 60k on....
No its the chain never had problems with tensioners.
i measured the chains new and old and there was a link or sometimes link and half stretched on the old chain.
