New Engine issue's Need Help.......
Guys,
I just got done putting my top end back together. New heads, cams, pucs rods and throttle body. When I first started it up I notice some slight valve noise in the rocker box area. I also noticed that my oil pressure was 35psi at idle. I gave it roughly 25 seconds but the noise and oil psi stayed steady. I lowered my push rod tubes lookoing for oil and the rods are dry. I suspect no oil is getting to the top end. Any thoughts?

My first thought is that you didn't prime your lifters, but had you not done that you would hear more than a "slight valve noise." A lifter that isn't primed will awaken the dead. OP of 35psi at idle doesn't sound excessive to me when the oil is cold, although I don't recall what it is on my bike, and aftermarket cams with higher lift will be noisier than stock--so maybe what you're hearing is normal. What cam set did you install?

My previous post was intended to induce though; I was only trying to toss out ideas to get the brain churning, think about things that 'could' be causing the issue(s). I am by no means, a mechanic nor wrench...and I don't even play one on TV or the Internet.
