front or rear main seals are out and you need a new oil filter. New Answer: If your old oil filter was a FRAM this could be the problem. It is a known issue that often with these filters the old gasket will often become detached from the filter & remain on the car when you change the oil filter, thus preventing the new filter from making a secure seal. Check the old oil filter if you still have it, to be sure that it has its gasket intact. If the gasket is missing, that means it is still on your car. You will have to re-do the oil change process as you need to remove the old gasket before reinstalling the new. Good Luck.
