i posted this in the engine forum also but trying to get as much feedback as posible before droping alot of money and wasting alot of time that i dont need to. I have a new 350 Crate Engine from Car Quest. I have a taping sound when the engine gets to temp. I have tried adjusting the rockers twice. replaced the locker nuts on the rockers. but it still starts taping again when it gets to temp. it sounds more internal then it does when i loosen the nuts up on the rockers. also when it starts tapping my oil press goes down from around 40 to around 10-20.
