Oil pressure question
 

So I pin my oil gauge when Im on the car, not under normal around town driving but when I romp on the car I pin the gauge. Is tha bad??

I would definitely put a mechanical gauge on their to confirm the anomaly. That's strange.

I'm not too familiar with the LS1 oil pump, but the LT1s have a pressure relief spring. If the spring gets stuck there's no return to the oil pan and everything is forced into the oil gallies. This can accelerate bearing erosion.

If your motor has for example, the Melling 10296 HV oil pump with the high pressure spring installed, then yea that would be normal characteristics of your concern. But if it has a stock oil pump, the relief valve might be stuck in the closed position.

The paperwork I have says "lsx high flow oil pump"

High volume or high pressure? Or both?

Stock oil pan?

best bet like stated would be to use a mechanical gauge to verify the pressure.
