Well the engine is finally back in my '63 car all ready (or not as the case may be) for Coughton Court but I have an annoying knock/rattle so i would appreciate your opinions on the my engine and the possible cause.
It sounds like top end to me. I've had the cam cover off and checked the clearances, all spot on except No 4 exhaust which has only 7 thou clearance.
Both chains are new as are the tensioners though it does sound to me like some timing chain rattle when I first open it up (ignore the resonance its just a loose number plate) and the knock/rattle that is my concern can be clearly heard at high revs though it is quiet at tickover.
Chain guides are all tight and I can find no obvious problems under the cam cover. Could it be bottom end?
Subject to your comments my plan is to replace the cam bearings and reshim with head in situ...waste of time or worth a punt?
Your comments and opinions much appreciated ...as this car is chassis no 400-00316 I'm desperate to get it to Coughton but running our of time.
For the record the engine has not been rebuilt just cleaned and painted and chains/tensioners replaced so the head hasn't been off.
