3.8L engine, has started plowing the seal off the oil filter. on 2000 Pontiac Montana

when you start the car the oil seal will fail on the filter. I have used several brands, does this on all brands. was told it was a pressure relief valve. replaced the pressuer relief valve in the oil filter area. It still blows the oil filter seal. need help.

could be the check valve in the oil pump. i would have it checked by a shop to confirm. Roy
