Pulled my dead engine out of the van today. Planning to tear it down bit by
bit until the leak reveals itself. Then will decide what to do. I'm leaning
toward a complete to overhaul with all new seals and gaskets right on out
to the tail pipe, a  complete  ring job on all cylinders, and a valve job.
All this will be done subject to what a crankshaft runout test shows. If
its to much, and it requires the case be split, the whole thing goes to the
scrap heap in favor of a Subaru Engine.
