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.
