No hot start low oil pressure

Brand new ICP
Brand new IRP
Brand new HPOP
Still starts COLD just fine
Still runs great after started
Still won't start hot unless drifted or pushed
Still no codes

About 365 EOP when trying to start hot

Any ideas?

IPR orings... Could have pinched one when installing the IPR. Could also be the dummy plugs and/or standpipes leaking by when hot.

I dont think I have dummy plugs. Its an 03. I was under the assumption that 04.5 and up have them. I took it to a garage and they dont even know whats up with it.

You need to air test through the icp sensor hole and close the ipr valve and see what leaks under the valve cover. If it's under the pump cover then you can blow air into the nipple that sticks up off the pump with a rubber tip blow gun.

Check the high pressure oil hoses under the valve cover.
