I Blew a ring & piston third from the front on the drivers side.

I will try to upload some pictures, and am hoping that you guys will think that I will be able to just hone the top of the cylinder wall and replace the piston & rings.

You won't know till you hone the cyl,, and see how it comes out.. Pic 3 isn't encouraging,, a sleeve may be in order..

hope it helps

Thats wut I b stinking....depending on the deal with the block it may not be worth putting a sleeve in it.

This is why a racer buddy used to order 12 pistons....granted his were not off the shelf but....
 
Have to ask....what happened? Drop sumtin down the karbanator?
 
Looks like it is damaged above the rings to me. Like stated above you won't know until you hone it. Take some measurements and see if the scoring is above the top ring.
 
That did not happen from a few seconds of acceleration.....................

Hard to tell from those. Might be able to bore it. That is NOT gonna "hone" out............

Otherwise, it's a new sleeve or a different block
 
That is Detonation..... Running lean as heck to pop a ring lan like that. You need some tuning for sure when you get it back running.

Looks like in the picture that it is Piston Material stuck to the cylinder wall. If so it should come off. Maybe it looks worse than it actually is.
 
I'd say it's coming out.........MAYBE get away with a hone, though most likely not, sleeve most probably, a single piston is gonna be a pain, doable but still a pain; hope you still have bob weight info.

Good luck!

Yup...."pressure" will not cause this....if it did diesels would be in big trouble. Form the pictures looks like there may be a crack in the wall. Gonna have to tear it apart. If it is just a run of the mill block I would just toss it....
 
sadly that MOTOR IS pretty much JUNK NOW.. prob need to be sleeved..no fixing it easily or cheaply..
 
You're taking it to the machine shop. They're gonna need to mag ans sonic the block. A sleeve may fix that but be prepared to buy a new block.
 
Does it look like, where the piston has broken is right above the ring gap?.....
