Do you mean that there is actually a "window" in the side of the block, created by a broken rod?
If so, surely that block is a write-off? Common sense (and cost) would suggest a new block would be the best option.

As an aside....remember back a few decades ago, when a Ferrari F1 car retired from a race, and the reason the Team gave for the retirement would be given as "perdita d'olio" (oil leak)?
Of course, had nothing to do with the rod poking through the hole in the block

Cheers,
Glen

I'm taking the engine to Survival Motorsports and in talking with Barry, he said the alloy blocks can be welded and be fine. He will tear it down and go from there.

That's pretty cool !! Do you think the rod over heated ? Or was it just a weak link ?

Yes, I think as long as there is no significant damage to main webbing, other vital parts of block, it can be fixed. It's the way to go.

Sounds like an oil leak to me

Doug,
“Numbers matching” on a continuation is just for fun. It’s something to mention in an ad but couldnt put $1 on its value.
That’s my story and I’m sticking to it.
