Newbee with bad clicking noise, lifters? low oil pressure?
I need some help! I have rebuilt my ls1, The short block is basically stock, new rings and bearings. I installed Patriot Performance #2013 Heads, Gm Hot cam (Yes I know but forgive me I'm new to the ls1),New Comp lifters, Hi tech 7.325 Pushrods, Hartland sharp Roller rocker arms, SDPC Ported oil pump, New o ring, I have read alot about valve train noise but I think My noise is louder than normal. I have 45-50 Psi Oil pressure cold 30-35 Psi hot. The noise sounds like 1 or more of the lifters is colapsing. I have heard about the o ring causing this but I did install a new one. Should I have better oil presure than this? Any help you can give me would be greatly appreciated!!!!!!!!!

confussed about noisy engine
Yes it jumps to 45-50 if you rev it up! the noise also gets louder as you rev it up until 2500 rpm when it fades but dose not go compleatly away, at about 3500-4000 rpm it comes back pretty load again??

The motor should hold around 40 hot. Sounds like the o ring didn't seal good. Also the 7.325 is a pretty short pushrod, any reason you used that short a pr? The heads would have to be cut ALOT to warrant anything shorter than a 7.35. This could cause the noisey valvetrain as geometry could be off.
