Would it be hellaciously expensive? You bet!

But it wouldn't be unrepairable.

Terrific. You can have that engine in your Discovery.

Don't understand the doubt, maybe I just work with really good machinists?

That said, for the cost involved, I'd just grab a good 4.0L Bosch block and build it up.

This is what the welds look like from the outside.

If your sleeves are moving, this seems like a good fix. 1500 bucks is a bargain compared to a 5k top hatted motor.

Good cheaper fix RMT and easier than pegging. Knowing exactly where to drill through is obviously part of the knowledge. Only issue for the future is if anyone wants to rebuild the block with new top hat liners but the majority end on the scrap heap way before then. 10 out of 10 for ingenuity in this case.

Why is anyone concern about the block been trashed after the repair? you can get a repairable block cheap, actually there is one in Craigslist for $300 in North Jersey, to me this is good fix, don't see it as a permanent solution like a top hat lined block but nevertheless a very clever approach. If someone don't have the budget to spend $5000 plus to rebuild an engine or perhaps have the common sense not to spend all that money in a vehicle that is worth $2500 after is fixed these is certainly a risk that I will take, well done MRT.........
