Leaking Expansion/Freeze Plugs
The engine is in the truck and runs great. MPG with TC was 9.4, nothing to especially write home about. The problem I'm having is coolant leaking out of 2, possibly 3 plugs. 1 left, 1 right, and poss...

No point in being intentionally vague here. You posted a detailed account of this issue presumably to share.
You haven’t asked your “machinist” what his magic solution is? Or you’re not sharing it?
So you’re going to drive down to Portland to figure that out?
This just doesn’t make sense unless you’re just secretly hoping the issue resolves itself rather than addressing it and checking this off the list or adding it to the list.
Strange approach.
That is a very strange response! I'm hiding nothing, nor am I being intentionally vague. I give information as it develops. I'm following the machinists instructions, it's his build and warrantee so I'll follow that. I said he has a fix called T-Block if the plugs don't seal. Having just talked with him, he refers to it as a Rebuilders Block. It comes in the shape of a cube, dimensions unknown, it will be here next week, and I am to crush it and pour into the reservoir. It will circulate through the engine and he says will seal any leak, period! He says it will not cause any clogging issue with the radiator or heater core. He says manufacturers put this in new vehicle engines as a precaution. II can't find anything on the internet called T-Block so I'll just have to see what it is when he sends it. You know everything about what's going on as I do up till now. Next update will be when I get the stuff and install it, then wait and see what happens. Until then, be patient. I'm hoping for a happy ending. The engine is running great thus far otherwise...
I believe this is the product.
That’s what I was getting at. He’s recommending a leak stop additive to the cooling system. Which you weren’t specific about. But it had to be some sort of stop leak.
And many/most of us have used the stuff before. Many times with good results. Probably bought vehicles that someone else used it.
And many have experienced issues as well.
All roads point to this being not only a temporary fix but generally significantly increasing the potential for other coolant flow issues.
The real question is that risk worth less than your time and effort?For a vehicle used in extreme duty and meant to be a reliable long lasting primary vehicle, doesn’t seem wise to me.
You know that as well.
One would think that if there was a magic product that didn’t have the potential to gum up good parts of the cooling system, it would be public information by now. I don’t think that product exists.
