S'all good...was a timebomb after last "rebuild". I dont think it was firing for a while. Intake had a pool of oil in it, and there was a lot of water/e85. Would smoke bad when stomping on it. Thought it just need a lot more crank case ventilation but I guess that was some of that oil getting burnt up. Turbo take it like a champ blades all look undamaged
pan blew out into the flex plate, broke one of the heads off the converter bolt so i need to try and get whats left out of it but seems converter/trans is all good.
had to take the pan off, removed windage tray, and take out/loosen the last two main caps to get the crank to spin and remove the converter bolts
seems the gm head bolts stretched a little also - removing with impact the whole way out felt bound up, will be going back to studs next engine.
