Did you put some sealant under the sleeve, and did you oil the pulley shaft before inserting the pulley onto the crank and into the seal? Does that seal have a tension spring inside it? It's a slightly tighter fit with the sleeve and if it's difficult to get in you can knock the small spring (if that seal used one) off the sleeve. Check the crankcase pressure by running the engine with the oil filler cap removed, but if it still leaks my guess is that you either nicked the seal during installation or dislodged the tension spring in the seal. If that happened, when you remove the pulley again you'll see the spring wrapped around the crank - you may need a mirror to see it. --- In dmcnews@xxxxxxxxxxxxxxx, Soma576@... wrote: > > Hey Group, > > Part of my engine pulling project was to replace a leaking front main > seal.
