It has some chips on them. Dont know if I can still use them. The cylinder has a scratch that I can feel.

SWEET2KSTANG · May 19th, 2009, 01:27 AM

forged pistons are strong, but not indestructable.

BoCFes · May 19th, 2009, 01:30 AM

Not the smartest guy out there, but could it have been a stuck valve? Figure the valve would be a lot more jacked up. Help me out here.

Ill try to take some pics tomorrow of the valves.

crazy old cuban · May 19th, 2009, 01:51 AM

it's hard to tell from the picture but it looks like extreme combustion due to stuck-up valves

BoCFes · May 19th, 2009, 01:51 AM

Cool!!!!!!!!!!

jrzybullitt · May 19th, 2009, 01:51 AM

Possible it sucked in part of a plug?

BoCFes · May 19th, 2009, 01:53 AM

I don't quite think it would be the valves but it looks and sounds like something def ended up in the cylinder. But damn.

Jakashh · May 19th, 2009, 02:06 AM

Due to detonation, the ring more than likely broke causing the damage to the piston. I have a Cobra sitting here with the same problem. His car ran way lean because of a vacuum leak. Now building him a new forged block.

^^hey do you still have my rear brake pads? the new ones?
