    How to clean out crankcase. Help!

    Doing a top end rebuild and want to be absolutely sure no debris got down in the crank while the cylinders were off.what's the best way to go about cleaning it out without splitting the case? Better yet how to I be certain I got all the diesel out of the case after I dumped some in there and let it run out the reed openings.

    Input greatly apprecited

    I'd probably get a solvent sprayer and turn the crankcase upside down. Spray up inside it with Naptha. Carefully turn the crank and listen/feel for anything unusual. It should be smooooooth.
