I have a feeling it was broken on the way in and just finished itself off along the way. I didn't put the shortblock together,I only dissected it.
I'd never claim to have seen many busted pistons, most were on someone's desk as a novelty but geeze. It must have been defective from the beginning. Who's is it? Les
Loods like a manufacturing defect to me. How it held on as long as it did is amazing to me. Who has seen the oil ring land fail? Les
I don't know for sure Chris.....but it started going down hill for sure after we left Bradenton. I was 2 tenths slower at Rockingham just 2 days later and we had similar air,my mph fell by 3. This happened on this very motor before I got the car if I remember right.I know they fixed the one piston that broke but I don't know if all the pistons were re ringed or not. Doesn't matter at this point. The motor is disassembled,the block is in the metal bin and the crank and rods are on their way to Arrington to be reborn in a 426 a friend is getting.
What brand piston? Where did the material go? Lucky it didn't do more damage. Did you do a compression test before you pulled it? Oil consumption bad?
The material didn't go anywhere....I am holding the land in the second pic. The ring was broken in multple pieces though. It didn't really burn oil too bad,but there was so much blow by the PCV system couldn't handle the pressure and the motor would push oil out the breather on WOT. Didn't even waste my time on a compression or leakdown....it was obvious the motor was hurt,we knew the cylinder walls were worn bad,hell they were worn when I pulled the heads at 30k miles,now they are shot, so I didn't waste the time on a leakdown.
