07 ISX Elevated Oil Pressure

[rtjohnson1982]

Hey guys! So lately I’ve noticed my oil pressure at idle is higher than normal, consistently staying between 32-40+ PSI where it had always stayed in the low 20’s. I know weather temps can effect this to some degree but it’s doing this in warm and cold weather. I looked into it and articles are saying it could be a stuck oil pressure relief valve but wanted to check with the man himself Mr. Rawze before throwing parts at it. I did get a EGR delete last year in case that’s relevant. Thank you!!
