No oil getting to my rockers but pressure on the gasuge I just recently had to pull my LQ4 out of my car to replace two pistons. If it matters it is a stock LQ4 other than ARP head & rod bolts with a MP T-76 turbo. The two clinders showed no sign of damage so I re-honed those two and replaced with stock pistons.
While in there I upgraded to Patriot Gold springs and the TRW push rods that the recommended. Other than that I reassembled it just as I took it apart. I have an electric autometer oil pressure gauge that is tapped into the fitting right by the oil filter. At idle I'm getting about 40psi on the gauge.
Could the problem be the dual spring doing something to the stock lifters? I'm lost so please help before I F*ck something up.

Are the push rods drilled properly? Put the old oush rods back in and try it or compare them at least. As the push rod moves up the hole in the pushrod gets covered over by the rocker so no oil comes out the rocker. As it moves back down the hole is opened in the rocker and oil comes out. I have to think there is some kind of miss match in the oiling holes???? or the geometry is that far off. How long did you run it this way?

Can you put your pressure gauge in the port at the top of the block behind the intake? Might have something blocking your oil passage st the barbell in the back of the block

Are you SURE there's no oil getting there?
I've never really seen a LOT of oil puddled up in a cylinder head...and even at idle with a valve cover off (if you can still plug in your coils...be careful) you usually don't see much oil flow up there at all until you rev the engine up a bit...at which point it will make a mess.
