JB Weld Epoxy would be my choice or find a way to 3D Print a replacement

Well, I used replacement glue, I don't think any glue was going to fix that one!   The good news is, the smoke bowls are a common part across a bunch of products, so I had one that fit.

Dunk it in thin CA, let it dry, then toss & replace.

I decided to skip the glue step.

Whoa.

Put it in a crucible and melt it down. Cast it into a cube, let it cool, then throw it into the garbage.

I ran across one of these several years ago, another instance of a specific batch of diecast from around 25-26 years ago going very bad!

I've had good luck with

Gorilla 2 Part Epoxy, 5 Minute Set, Incredibly Strong Bonding, .85 Ounce Syringe, Clear, (Pack of 2)

I have used Gorilla gel and let dry over night have repaired snapped off engine round cover mounts   which were broken off with great success ,you can file and sand to fit and holds!

Too late Alan, it's already in the trash!  I have several of them in my parts drawer, so I wasn't investing any time on this one.   For stuff like diecast in that shape, trying to make that whole and back in it's correct shape just isn't worth the effort, especially since I have more of them.

I repair plastic shell posts all the time with plastic straws or brass tubing and JB-Kwik, that's a while different matter.  I don't have replacement shells laying around.

Honestly, John posted this as a joke. Trying to save a deformed small-parts casting suffering from zinc pest this badly makes no sense. The casting is compromised. Find a replacement and move on.

Compromised is putting it mildly.  I picked it up and crushed it in my hand, I felt like SuperMan!   I was kinda' amazed that I actually got smoke out of the smoke unit before I took the shell off and saw the carnage.

I wonder what kind of glue I use to fix this MTH smoke unit?

Try the miracle black paint the PennCentral used to use on truck side frames

Must be powerful stuff if it could fix that!

Ha! The good old Penn Central..."back in the day," on their FL9's, they used plywood on their sides!

Not plywood, structurally, supporting amazingly engineered stuff just like the amazing metal repairing crack ceiling, black paint. Lmfao

Amazing paint, repaired trucks on GG-1s and other big electrics…….no zinc pest or fatigue cracks for  the PennCentral………..super duper paint, does it all!

This must be a common problem. I have had to rebuild a few MTH smoke units due to them being very pesty like yours. Luckily MTH keeps them in stock. "Replacement glue" very much in order.

Send it to Phil Swift for his Flex Seal commercials.

Your not serious that you would glue that?  MTH use to sell the fan house and element house as separate units.  There was a run of some diesels/GT that had that issue.  G

No, I obviously wasn't serious about gluing that, it was supposed to be a joke.

I had several of the same post length in my parts box, so it was a quick swap to solve the problem.   I've run across probably half a dozen that looked like this over the years, all but one were PS/1 models, and I believe all were diesels as I recall.  I was astounded that it was still seemingly smoking properly until I took the shell off and the broken post fell out.
