Hi all,
I'm am working on a 74 W200 with a 360. When I first start the engine I have 50lbs of oil pressure, but after it warms up and idles down. The pressure drops to about 25lbs at idle and 40 lbs at operating RPM. It has a new edelbrock cam and lifters with new cam bearings. All the other bearings are within spec and the oil is fresh 10w40.
So why the pressure drop? Am I worrying about nothing?
