Where exactly is it leaking, at the threads, or at the bell housing...if it is at the threads then it needs to be removed (make sure you applied significant teflon tape) and re-attach.....if it is at the bell housing then there must be something inside making it not able to seal. or it is a bad backflow. Let us know what you find!
