No oil pressure.. help?! 05 GTO ls2
Just pulled the motor for a rebuild. Put a big cam in and it drove great after the tune, took a thousand mile trip and it was fine. Im driving it yesterday, went about five miles no problem, then stopped in the parking lot and it idled for 30 seconds, all was good still. Cut it off, 5 minutes later go cut it on. The check oil light comes on (not service) it is full and still fresh. I go to crank it and it cuts right on but the valvetrain and maybe lifters are screaming, so i kill it and have it towed home. Run the scan tool and draw 0 psi, remove the valve covers and the rockers are still at 22 ft lbs but i can push the pushrod side of the rocker down to where the spribg side liffs up about 1/8 in more or less. The car still runs well.
I knowbi need to replace the pump and probably remove the heads to check the lifters but any other ideas would be much appreciated so i dont have to tow my car back home in two weeks.
