lol yeah i know, exhaust is pretty loud atm, thats because its dual cherrybombs dumped, waiting for more money so i can finish the exhaust all the way back.
I used a redneck stethoscope (wooden hammer handle) and notice the noise doesnt come from the valve covers, i hear it when i put the piece of wood to the lower intake manifold though. i'm so confused on whats causing this. all the lifters are good and squirting oil so i'm at a loss here. dont know what else to do.

I'm feel'in your pain, very frustrating. I have a steth but find it way too sensitive and hard to pinpoint, low tech wood probably works better.
If the sound points you to lower intake then maybe that should be your next investigation - follow the evidence.

If it is still the lifters then the only thing I can think of is a blockage to the oil port that feeds the lifters. You'd have to look at an oil flow schematic to see if this is possible. The pressure gauge may read good pressure because it is downstream from the blockage. I can only think of sludge as blocking the port.

If it was a sludge problem wouldnt the rockers not be recieving oil? I got oil to all of the rockers.

Without an oil flow schematic I can't answer your question. You can search the web for one.
What else do you think it could be?

Well i finally figured out what the noise was... It wasnt lifter tap like ithought. It was actually wrist pin knock, which sounds very similair.
The way i found out was because... On saturday night i was on my way home from picking up a lift kit and about 1/4 mile from my house the motor threw a rod, i limped it home by coasting down the hill. Once i saw the long trail of oil/coolant mix going up the street i knew what had happened. The wrist pin broke loose and took out a coolant jacket and then ejected the rod out the oil pan. I found a new motor which i'll be installing this weekend hopefully.
