You can apply a new circular seal to the front of the engine after removing the front pulley and cleaning the area around the crankshaft. Others will chime in on the correct seal and how to prepare it and seal it to the engine.

Hi Harold,

A rear axle cap felt seal # 2510B fits well on the crankshaft and is a just tight enough fit behind the pulley. It likely will get you through the driving season. Good luck with your project, Bill.

How much is it leaking? Drip? Steady stream? How old are the seals? Has the engine been sitting for a long time and seals dried out?

Harold, If you Google my name with crankshaft oil seal MTFCA you'll find several threads and some part numbers. Toon has posted some really nice pictures to give you the idea how to stop any dripping at the front crankshaft. I really like the way he did a little surface sanding but if your engine is assembled it's not required. I cut the seal opening up all the daisy pedals.

I like to use a seal with a larger lip and make sure to fit it so you don't have any sharp edges. The Real Key is clean the surface of any oil and grime and Make Sure to use ULTRA BLACK made by Permatex. Let it dry over night and WhaaLa no more leaks that cover the under side of you car from front to back from the crankshaft.
