So I did a partial rebuild on a 3.0 where in I replaced the pistons, rings , connecting rod bearings, and crank bearings.
It seemed to be going pretty well good compression (185 on all cylinders) started right up, had some carb problems but a rebuild fixed that. I did a couple test runs at the lake to figure things out and was satisfied enough to take the family out. A couple hours into our trip I noticed the oil pressure waning. It had been around 40psi but was now hovering around 20 even dipping to 10 no matter the rpm. We cut the trip short because of that and a broken alternator belt.
Today I changed the oil and filter but it didn't seem to make a difference.
The pressure seems better cold at 35-40 but gets worse the longer it runs.
Anyone have any insights? I've never had an oil pressure problem in my vehicles so I'm not sure where to start.
