G wagon idle noise
Hi all, a friend has a a 1992 350 diesel G wagon with about 150,000 miles.
At idle it has what can only be described as a rythmatic clatter which disapears as the revs are raised. It has no effect on the running of the engine which runs well with no smoke ect. I think it is coming from the timing chain area so I pulled the cam cover off to have a look.
The only thing which seemed a little odd to me is the chain damper to the right of the cam sprocket has with slight finger pressure a lot of movement (1/2 inch maybe a little less?) front to rear. The chain does not appear to be loose so perhaps replace the tensioner on the left side of the engine first?
Thanks in advance
