Yes, usually happens for one of two reasons. Either a poor quality filter (Fram comes to mind) or excessive oil pressure. Are you still running the stock sized oil filter? Is your oil bypass plugged? If yes to both that is a deadly combo. On start-up the oil pressure is really high and the little filters can't flow enough to keep up. Since the bypass is plugged, all oil has to go through it. I have a biggie oil filter kit and a blocked bypass. Even with the huge filter area, I had the filter crush internally while I was breaking in a cam (high start-up oil pressure, high RPM). I now let the car warm up and the oil pressure drop down before I flog the car.
