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