Where can i get a repair sleeve for my crank seal i guess its called the front seal the one on the crank faceing the passenger side of the car.. the seal went and is leaking onto the exhaust and i replaced the seal hard job but the crank was grooved and it was all put together cause i was at a rental bay and was out of time now i want to go do it all again with a whole new kit with a sleeve and anyone know how they go in? or how hard it is? please tell me i dont need a new crank this engine runs solid and this is the only problem
