Is this block junk? This is what I found in my friends 14,000 original mile LS6. I Pulled the heads because it was blowing coolant through the exhaust. Was hoping for just head gaskets but found a broken no.7 piston. Then felt what I hoped was a gouge in the cylinder wall but looks like a crack. The motor is still in the car so I couldn't look real close but I stuck my phone down there and took these pictures. ...Now what? ..Order a short block from somebody?? ..Worth sleeving an LS6??http://i1189.photobucket.com/albums/...kcylinder1.jpghttp://i1189.photobucket.com/albums/.../crackcyl2.jpghttp://i1189.photobucket.com/albums/.../crackcyl3.jpg |
Oh yeah, It was boosted. |
Cracked piston 90 % time pushes the aluminum out and crackes it. If you can see from inside the water jacket it will be cracked also. Get a new or used block. |
Time for a new block |
Ouch, Stock? N/A? Shot of nitrous? |
Yep junk it or get it resleeved. |
No bueno! |

Any ideas on cost to resleeve an ls6 block? Is it ok to just sleeve the bad cylinder? |

Only $1200 to make a 427! (plus rotating assy of course), doesn't seem bad. I'd be happy to have @400ci and reuse the LS6 heads. ..What cubic inch would I be at with keeping the stock crank? |
387cu.= 4.125 bore x 3.622 stroke. Don't you have to use the evans water system with the darton sleeves? |

Swung by to talk to my machinist today. He didn't seem to mind the crack in the cylinder. He said he can just sleeve that cylinder only since he is machining them all for 3.905" pistons anyway. He said $250 extra to fix the bad cylinder. I thought it sounded fine to me. Thoughts? |
Call Steve at RED and talk to him about it. I can already tell you will advise against sleeving just one cylinder and he is an expert. http://www.raceenginedevelopment.com...4927/index.htm |
