2004 Ford F250I HAVE DONE AN OIL CHANGE ON MY TRUCK AND BOUGHT MOTORCRAFT FILTER FL820S. But when I screw the filter on, it does not fit tightly against the filter adapter. There is a gap and is now leaking. It is not cross threaded and the new gasket is intact.  The old gasket is not still left on. What have I done wrong?


RESPONSE

Oil Filter

Try putting the old filter back on and if it works fine then the problem is with the replacement filter. The Motorcraft oil filter part number is correct. There may just be an imperfection with the filter. It happens sometimes, but not too often with filters. There might just be a slight burr on the threads or something. If you find the old filter does the same thing as the NEW filter now, you will need to look closer. Make sure the adapter threads have not come out to far and do not need to be re-seated.
