I don't really want to flood this thread with needless updates so I've stayed away for the moment. But the engine is out and for sale if anybody wants a boat anchor or coffee table. LOL
Seriously I think it might be a "re-builder". The oil filter didn't seem like it had an excess of metal shavings... IDK Doesn't matter
The Harbor Freight engine hoist which normally is quite inadequate when it comes to length did VERY well here. Just used a long chain and whola the engine is free.
Still waiting for my buddy to finish (or even start) welding my M90 so I can fit it to my 4.3 and get to rebuilding that engine.
