I just bought a 96 Jeep Grand Cherokee Loredo after sitting for a few years. It runs and drives but why does the oil pump lose pressure? Oil pressure comes up but only for a few seconds and then drops to zero. I added a can of seafoam because that's what was recommended by everyone that I asked about it. Even the parts store guy. Still same thing over and over.
