Default Re: Front seals

The seal was installed with the lip towards the interior of the engine. I pulled the pulley and found the seal looks ok, measures 1.50 with the crank being 1.3135 and the gap to the seal at .09375. My pulley has the spiral as part of it, not two piece, so I put a reddi sleave on it that measures 1.6345. It seems the seal should be fine. What I think is happening is oil is going under the seal and coming out, the trough that the seal sets in is large on the pan portion and deep in the center. I am going to try a sealer on the seal to pan, put it back together and give it a try. I will let you know.
