Mike,
My motor has less than 1500 miles on it and its been out twice. Inspected and replaced with new pump from Precision
Oil Pumps both times. Just good insurance before you bolt everything back together. I would drop the pan and replace the pump. Also I run Shell Rotella
oil and have been real happy with it. My
oil pressure looks like this:
Cold oil pressure is over 100 lbs, warm 35-40 at ilde (1100 rpms) running 65-70mph 75-80 lbs.
