anyone ever had a leak from the oil pressure sending unit and/or replaced one? there is a good amount of caked on oil crud on my passenger cylinder bank (4-6 i think?) and i can trace it to the top of the bank, forward most. it's def caked on the post leading up to the sending unit but since that post isn't very high, i'm not 100% sure it's the culprit as it could very well be coming from the top of the bank and simply hitting the post as it blows back. so is there any chance it's leaking from the bank top side? i'm HOPING it's just the sending unit/gasket.

i have 50k miles, a lot of track days and pressure seems like it's reading fine, btw.
