No way. Piston assembled to con rod, then installed into block. Depending on engine, that rod would have been flailing and punching holes.Neighbor down the road had a motor put into a truck, local diesel mechanic purchased a 5 year 50,000 mile engine from east coast. Neighbor drives it and detects a tick or mild knock, not sure. Anyway, engine gets scoped and there's a freaking missing piston??? Connecting rod is there, not sure about the pin, but no jug??? Anyone want to speculate if that piston could have never been installed, cause that's what it looked like??? Weird.
