Hey guys I've read a ton of threads regarding high oil pressure. Recently installed a built 6 bolt w/o balance shafts.
I understand there's a good chance of high oil pressure when you remove the balance shafts and I need to port the OFH relieve valve which is on my list to do. There is currently an oil leak at what appears to be the front main seal which I was thinking was due to high oil pressure with the new motor.
I installed an AEM oil pressure gauge and warm up idle oil pressure is around 15psi which seems about right from what I've read. I've heard the oil pressure should increase about 10psi per 1k rpms. What I'm unsure about is should oil pressure raise 10psi per rpms if you're at WOT? Part throttle? Does it matter?
I'm currently sitting at 70psi at 3k rpms (seems high) while cruising but when I lightly accelerate (part throttle) up to about 5k rpms it only seems to rise to around 85psi. I haven't really gone full throttle at this point due to lack of fuel so I'm not sure what it would end up at unfortunately.
I guess my big question is does this seem abnormally high? Would this cause the front main seal to leak after a couple thousands miles or is there a chance the seal is the issue not the oil pressure? Thanks for any help, it's greatly appreciated!
