[LeakProof]

I just split my 3.0 yesterday. All I had was one broken head stud to lead me to this point. I had gotten tired of contemplating if I should or shouldn't, so I figured With the Winter season approaching I might as well. This way I could check everything out, Reseal case, clean case ( in case I contaminated it upon tear down), Replace #eight o-ring and main and intermediate bearings.
Then my 3.0 ,107,000 mile engine shall be leak free.
Everything looks like new within the case except perhaps the intermediatee bearings.
The one frightening thing was hammering the case to split it. Think next time a block of wood is in order.

Anyhow, best of luck to you.

Leakproof.
