Guys take a look at this LS6 block and tell if it can be repaired

Got an error message...

 

I got an error as well. If a TIG can get to it it can be fixed, and if done by a competent welder it will be as good as new.

 

sign out next time before you link to a picture otherwise we'll get the security error. wish i could see the pic tho!

 

Me too, if its in a place that can be accessable PM me and I can have it fixed for you.

 

guys,

try the link above, I think that I fixed the link

 

that looks iffy at best, the sleaves might have shifted so they will have to be re-honed and i don't know how that would workk with the crack going throught the entire length of the block.

 

I can get that fixed for ya, just PM me.

 

Being an engineer I have a tendency to look at issues like this from a different perspective...the question I have is "why did this block crack between the cylinders?".
The only answer that I can come up with is that there was a bad pour when the block was cast. If the molten aluminum does not flow into the space between the cylinder liners or if it cools prematurely then there will be a weak point.
If I were in your position I would use this block for a MID sleeve project or perhaps sell it to someone for that purpose. While I have done some fairly complex welding I don't believe that I have ever seen a weld done on aluminum when it is this deep and bounded on both sides by steel.
Keep us posted on what you finally decide to do with this block...

 

What you will have to do is cut the 2 sleeves out and then cut the crack out to the water jacket and the weld it all back up and resleeve it. Not hard just time consuming. I have seen it done on various aluminum engines many times.

 

I would take it to a reputable machine shop in your area and let them look at it if it can be fix.also prolly depends how deep is it.good luck.

 

A good core block can be had for a few hundred $$, much less than the costs you will incur fixing that one.
