High oil pressure b58

So I was leaking from my valve cover gasket and I decided to replace my gasket with a new one but I though since Im taking my valve cover off I should aswell install pcv head port block off pins since I was planning to go big turbo soon. Anyways after everything was done I ended up getting a code for a crankcase leak I will show pictures of codes on here. I aswell got a code for high engine oil pressure. I added a BMR catch can still didnt fix the issue. I am running liqui molly 5w40. Does anybody have any suggestions ??

I decided to see if maybe its my oil pressure sensor I left my car sit for 6 hours after driving it then I checked my dashboard for psi on the oil pressure and it was sitting at 14 psi could this mean its a bad sensor. I mean I should be having 0 psi if the car is completely off no ?

111 psi is way too high, with my old oil pump, my oil pressure would spike to about 102 psi when WOT, no high oil pressure codes, after changing the oil pump, my oil pressure never exceeds 80psi no matter the circumstance and I can measure my oil level Youre probably looking at a oil pump replacement very soon unfortunately.

Check with your tuner

Mine seems to have been resolved with a tune revision from AshtonPJT

I was scared shitless that it was my oil pump but it was most likely a glitch in my tune after I added a Dorch HPFP, S58 injectors and a Pure 800 turbo

Mine starded happening after doing my valve cover gasket and installed pcv head port pins I took them off and still does it Im taking it to speelogic for a diag I dont think its my pump due to the fact that it was working before the gasket also my car is a 2021 so I highly doubt it. Ill keep yall updated. Also weird enough my code shows as an inactive code which is super weird. Maybe a retune is needed but I also dont feel like paying 1k again 😫. It could be my oil as Im running 5w40 I think ima go to ow-20 or 30

Inactive codes are self cleared by the system no need to worry about them

This. Oil pump is broken. This is the telltale sign. Get it replaced before it costs you an engine.
