Is there supposed to be a gap about 1/8" between my Motorcraft filter and the oil cooler (where the filter screws onto)? I tightened it up by hand as much as i could and there's still a gap. Does the oil cooler have a black rubber gasket around it (the side where the filter screws onto) that maybe should seal the gap? I've changed the oil 3 times before this (all with small gaps between the filter and the cooler) and had no leaks until yesterday's oil change.. Can someone enlighten me as to whats going on? I cleaned the surface of the cooler and there's no old filter gasket stuck on it. WHY IS THERE A GAP?!?
