Sorry for the late reply but I did not have the chance to work with the car before today. So I changed the oil filter with a MAN filter, changed oil to 20w-50 and installed the manual gauge and on cold start idle the pressure rises to 30 psi quickly. As the oil gets hotter the pressure drops and it drops all the way down to 1-2 psi fully warm. And 2000 rpm roughly 10 psi and 3000 rpm around 20 psi. I am starting to think that either main bearings or rod bearings may be my issue or both. What should be my next move? Can I inspect them or change them by only getting the sump off while still having the block installed?
and what should I look for?
