Re: O/T-FSJ; AMC 360: low idle oil pressure like 258?
I am not sure about the 258 but all the AMC V8s have an aluminum housing that the distributer, water pump, and oil pump goes into. Over time the aluminum wears out. I dont know if there is an easy fix or if you have to replace the housing. Maybe try running a heavier oil for a while like 20-50 and see what that does.
