did you change the oil after it was sitting for a few years?
did you use the correct viscosity oil?
what oil filter did you use, they sometimes can cause issues and you may want to try and install another one.
lastly you would have to do an oil pressure test to determine if the pump and/or bearings need replacing.

I change the oil and I'm using a K&N Filter I haven't checked the oil pump yet but I'm on my way to get a diagnostic now I update you later
