One of my turbo Mopar friends was at the drag strip going all out when his mixture went too lean and he melted one piston at mid-track. He nursed it back to the pits, where he and a couple buddies pulled the cylinder head to assess the damage. "Oh, we just melted one piston?" They proceeded to drop the oil pan, remove that rod/piston combo, installed a stock replacement, and bolted it all back together in time to get in some more passes that night.
Me and Karl did a clutch on his 4runner in the dirt parking lot in Delta between courses with hand tools and no jack. We just put the transmission on Karl's back and he did a push-up while I wiggled it in LOL.
