Using Epoxy to reinforce coolant seal walls
I'm currently rebuilding my 13B engine for my 1992 FD and I'm replacing the center housing because the coolant seal wall collapsed into the coolant passage. The rest of the housings look great with the exception that some of the seal walls look too thin. I'm thinking that they're stock size so I don't think buying a new housing would be any better. Some seem safe at 0.10", but I've measured some walls to be 0.05" and I'm concerned that they will be the next points of failure. I'm thinking about using JB Weld Epoxy to line/reinforce these walls. I see no results about this idea, so I'm thinking that this may be a stupid idea. Would it be safe?

Not a pro builder but IIRC the wall thickness should be uniform. If it’s not, the iron imo is junk. And yes, JB weld sounds like a hack job that won’t last and you’ll be pulling the engine back out and apart to do it all over again in a couple weeks or sooner.

Spend the extra $1000 (if you buy new) and save yourself the hassle of having to tear it down again. Only time I'd use something like you're describing is if its a proven race engine that's spent hours and hours on the flow bench and would be rebuilt in 20 hours anyway.

Welcome to the board.
I suppose this is one of those things that can be considered a good concept, but not necessarily a good idea. While I have known of people using JB Weld (or similar products) in engines, I don't know how the ultimate outcomes of those cases. I do know that I would not. So that is what I would advise someone in your position to do. Just get an intact housing and rebuild with that.
