2001 Saturn Oil pressure light flashes Sign In

2001 Saturn SL2 1.9 liter with 155,000 miles. Engine was rebuilt upper and lower after daughters boyfriend ran engine with no oil which froze the engine. Had the block, head and crankshaft repaired at a reputable engine machine shop. Also put a new water pump, oil pressure switch, and oil pump. Everything is new. I still have a low oil pressure light flashing after engine warms up. Oil level is fine. Replaced oil filter twice. No difference. Any help would be appreciated.

Sounds like there may have been some errors made in rebuilding, possibly in main bearing fitment.

The bearings were installed and verified with plastigauge for proper clearance specifications. I hooked up an oil gauge and am reading 37 psi when first started then slowly creeps down. I turned the engine off once it got below 20. BTW I had also verified the pickup screen is clear, no blockages.

If you're seeing 20PSI at idle, that is not too low. It can go as low as 8 to 10 PSI and be safe.

If i let it continue to run it will drop to 7psi, however , when i accelerate and then decelerate at this level the engine wants to stall out.

You might try some different oil but it's looking like there was some errors made in measurements.

Guess I will be pulling the engine again. I tried two different oils and oil filters. Used 10w30 full synthetic and fram oil filter the first time and 5w30 full synthetic with Purolator "Pure One" the 2nd time with no difference.
