Just the second I was calling it and shutting it off it dropped a cylinder and was smoking or antifreeze. Don’t see any coolant where it shouldn’t be so maybe it was oil smoke. Shut it down so fast there wasn’t much smoke. Headed to the machine shop now to see how hurt we are. I shouldn’t have focused so much on keeping the lifters spinning. It all got away from me so quick. Broken in 10 engines and never had any problems. Guess I had it coming.
