I am working on my 1997 Oldsmobile Cutlass; it is an automatic; 3.1 Liter; with 155000 miles. I recently had a lifter that was sticking and therefore replaced the lifters and had the heads resurfaced. While the engine was apart I noticed excessive sludge build up in the lifter valley and head area. I cleaned the lifter valley and flushed the pan the best I could without removing it prior to putting the engine back together. In attempting to start the vehicle now the oil filter gasket blows off the car. I have tried 3 different types of filters and same result with each. My question is could sludge have plugged the oil pressure regulator? Any help with this issue quickly would be wonderful. Thank You.
