Me again......
With my cam supplier away on a looooooooong holiday, and the 50th fast approaching, I decided to put the original cams back in. All went well, timing/verneirs sorted ect.
On engine start, there was a quiet tick for about 40 secs, which disappeared before I left the driveway. All was quiet for about 6 or 7 miles, when the loud ticking started again ( I was taking it very easy ).
With the followers apparently in good condition and the oilways open, why would this come back? Is it possible for a follower to be faulty? Should I replace them? Or is there anything else which could also be giving these symtoms? A broken piston ring wouldn't disappear, would it?
The engine's been well maintained and only done 15,0000 ml.
PS. After a dry fortnight, with no car, it started raining just as I left the garage.
