Ok, The sweet deal that was today. I had just got my new rear end in today. I was going to take it out for some racing. I started it up. I had my normal oil pressure which is about 65 psi at idol when it is cold. The engine may only have maybe 200 miles on it. I drove it around the block twice to see it the any thing was rubbing. I did not get on it at all. Pull in my driveway and I look down at the oil pressure. I have about 10 psi. It seems to be erratically be fluctuating between 5 to 15 psi. Usually when It warms up it drops down to about 45psi at idol which is normal but it only got to about 160 on the temp gauge. any theory's on what could be causing it?
