Low oil pressure 360 amc
I'm having some oil pressure issues with my AMC 360 in my 79 CJ5 . The pressure is good, about 40-50 when cold but as it warms up it drops down to around 5 or so at idle. I've had the oil pump rebuilt with a NAPA kit and it seemed to help a little, but not very much. Switching to 20-50 oil might be part of this. The engine was supposedly a fresh 5000 mile ago rebuild according to the previous owner. I replaced the old mechanical gauge with a new SW one so that’s not the problem. The only thing left that I can think of is a bearing problem. Has anyone had a similar problem? Any ideas?
