Oh wait, do you mean possibly that the TO bearing and shift block assembly is not retracting all the way when you left off the clutch and the presure plate has not engaged the disc causing it to slip?? Maybe I am following you now.

What about putting some more bolts in the dust cover to allow less space for mud to go into your bell. I know the dust cover on these engines have a few open bolt holes. i added a few bolts to mine to try and seal the whole way around.
