OK so I lost a cylinder due to a bad injector. It melted the piston and the exhuast valve. I honed out the cylinder and removed all the aluminum build up.
Now I have three scores that i can barely catch a nail on. Can I get a couple opinions on this as far as life, blowby, resealing in time and saveable??

 

May be a bore and new pistons nothing crazy on the bore.MAHLE pistons my guess is as good as yours.

 

Damn, sorry to hear this about my truck's twin! Hopefully some other guys have some good input on this..i have no clue either. Anyways good luck Andy

 

Thanks John, I dodn't think sleeves where an option if they where this engine would be the best ever!!! I work on tractor trailer rigs and when they drop a valve and destroy a cylinder I just pop out the sleeve and put in a new one and piston and head and they are off again for another million miles! I honed it down to two scratches maybe .010 deep can't grab it with a finger nail but you can see it! Due to money constraints I'm gonna have to run it and see how bad the blowby is. Call it an experiment in cummins resiliency!

 

Both sleeves and oversize pistons are an option on the ISB. Just depends on how bad the damage is and how far you want to push the performance.

If you can get a good hone cross hatch run it with the grooves and see what happens. You might be surprised how well it will work.

 

yeah it looks good first I used the dingle ***** and then did a cross hatch with the stone hone! Besides the two lines running up and down the cylinder it looks great! I'll keep you all posted on the results! Piston and rings are on the way!

 

wow, sounds like you have a nice place to do work on your turck, pretty cool im very interusted in the out come, hope something like this doesnt happen to my truck but im fully aware if you want to play you gotta pay! good luck dude

 

Damn dude if I had a space like in your sig pic I'd be in heaven! tell me where it is and I'll bring the tools!

 

haha that was my old shop i no longer work there! i live in vt and work on power lines, it sux big time, but i get to drive a straight six morooka and go mudding all day....miss the shop tho

 

Well at least I have a roof over my truck! Rain is coming! Cylinder looks good but I wish they made a mobile bore to cut it striaght! hand hone is as good as it's gonna get! I'll put the piston in tomorrow!
