my oil pressure goes from 65 to 30 after 1/4 mile pass 3 years no prob. 65 all the time now it jumps after a run then goes back to 65 on return road open to ideas
I had this problem on a 15 sec car. oil pressure was fine until i hit the brakes. lifters would start clattering and wouldn't stop until i shut it off at the pits. check oil level and it was up.
Added 1/2 quart over full, and problem went a way(thought it was a bad dip stick) a year later, pulling the motor, and then pulling the pan. that's when i found the real problem. the pick up tub was tilted due to a small dent, right were the pick up was:banghead:
