Resolved Oil pressure regulator bolt diameter

[AWD-Tony]

Did the first oil change after the 500 mile break in going from 10/30 to 20/50 and now my oil pressure is a bit high, 80 cold start and 30 warmed up. Plan to shim the oil pressure regulator on the ofh. Does anyone have a spare laying around to give me the diameter of the bolt so I have a crush washer handy? Not sure if it’ll keep leaking oil while I have the regulator bolt out.

Edit: I let it warm up a bit longer and got it to 23psi. Still want to shim it

Thanks, Tony

Remind me tonight if you haven't gotten an answer.

Got it. It’s 17.78mm and you don’t loose much oil.
