Default ot sure whats up..

my uncles motor froze up this past winter, indy block with screw in freeze plugs, he sent it back to the shop he has delt with for many, many years never had a problem and they always helped him out, well they sent the block back to indy to have it welded up, when they got it back they call and told him he needed new pistons,{ this is a 572 ci that was built less than 2 yrs ago with only about 15 passes } they said that when the block was welded the cylinders shifted or something like that.. i,m not sure what all they do when they weld it up, but seems to me that some where like indy would have ways to keep this from happing.. just want to know what yall think...

NOT, can't predict what will happen when the block is welded.

The cylinders will distort from the block freezing, that probably distorted things as much or more than the welding.. Think about it, if the freeze pushes hard enough to crack the block imagine what it does to the cylinders, as far as that goes to all the block dimensions.

just found out that they had to remove the sleeves before welding. when they put them back in they were to far out to be rehoned. they have to rebore it, it was already at the max bore of 4.5 with the heads that are on the motor. but they said there was a little more room. guess that the reason it was sent back to them ,to make sure it was right.....

If the sleeves had to come out anyway I would've thought they would just go with new sleeves and bore & hone to fit the pistons he has.

Really, antifreeze is cheap, new blocks and machining are not.
I drain and refill mine before it even thinks about freezing.

I usually drain the radiator and block before it gets cold enough for that to happen. On my old car I couldn't get to one of the block plugs without pulling a header. I drained the side I could get to and got busy with other stuff and forgot about it. Sure enough it froze what little water was in that one side and cracked the block. This was a stock block and after I tore it down I found a problem with the main journals that rendered the block junk anyways so there was no loss for me on that one. With the way the weather has been this year I have had to drain my car after test-n-tune. 70s one day and freezing the next.
