Thanks for the quick reply Kevin.
I think you have hit the nail smack bang on the head I know of another garage that told me they had fell for this once but it never clicked until you just said.
Thanks again

It would be nice to get a comparison wave form still to show good and bad crank and cam relationship and prove my findings.
It would be much appreciated if somebody could get their hands on one cheers.
I might even earn some brownie points
