Just fitted a new donor cosworth engine,, when it was running in the workshop it was so quiet no tappet noise or anything, left it running for 10/15 mins,, to get it warmed up as well
Just give a good run and the tappets have started to be noisey, it sounds like a different engine
(
Also the Oil guage goes up to 8bar and doesnt move while the ignition is on..
Any ideas???
