One of the pistons broke at the oil ring groove. All the way around. That part was at TDC. The skirt was still in one piece. Going up and down with the rod. Never hurt the cylinder wall. Dropped the oil pan. Pushed the rod the piston out. Installed new piston on rod, new rings. Installed everything back in. That motor ran for at least 6 years before the it got sole to someone else. :tup:

Can't imagine what that would be like if you weren't expecting it. We knew our pistons were toast before we opened it up and found this:

Put a LT1 350, 350 HP motor out of a 1970 Z28 into my 1976 Chevy 4x4. 3 months later. Cruising down the road. Motor started running ruff. Turned around a headed for home. Got 2 blocks from the house and the motor died. Buddy towed me home. Dropped the oil pan. It was full of metal shavings. Buddy turned the motor over with the key. Me under the truck watching. The back part of the crank. Behind the 2nd main bearing turned over. The front part of the crank didn't. The crank broke right behind the 2nd main bearing. LT1's have a forged crank too. :icon14:

Driving my old 1998 Ford Mustang GT on the highway and I heard a metal clanking noise during the drive and when I turned on to the exit the car shut off. I tried to restart it and no go. Turns out the 4.6L 2V V8 had three rod bearings fail and two of the connecting rods bent. Epic failure!!! Needless to say I will never purchase a Ford vehicle again. The 1998 Ford Mustang GT I owned was a real lemon and very unreliable and it only got worse as I put the miles on it. My old 1998 Ford Mustang GT I owned was fun to drive though when it was not in my mechanics shop or at the Ford dealership service department being repaired or found on road dead or on a flat bed tow truck.
