390 Oil Pressure Improvement
By Allan - 10/22/2002 3:08:00 PM; IP 12.13.226.18
I've got a 65 Tbird with a 390 that has the classic low oil pressure at idle problem. I replaced the oil pump with a standard flow pump about two years ago when I changed a rear main seal so I don't suspect that this is just a pump problem. Other than that the engine runs fine. I've been told that oil pressure could be improved by dropping the pan and changing the bottom half of the main bearings. Is this a useful thing to do to help this problem? Is there an easy way to identify the size of the mains with the crank installed? Would changing the rod bearings also help?
This thread, so far...
