Pipe is screwed in all the way by the look of the last picture. May not be any treads left in the block to turn new pipe into. You would have to get a new pipe with longer threads to go in more. Most standard threads lengths are about 1" long depending on pipe size. Would need pipe dies to make nipple longer. Noel.

Thanks. I found a product I am gonna try as a Hail Mary before I try tearing down to get welded or engine swap. I'm taking pictures and will post an update when I'm done of it holds up, or if it fails either way I guess so someone else can learn from my mistakes hopefully.

Thanks for all the advice so far guys. And no it's not JB Weld.

cmn, good luck on that hail mary, that is kinda what I was getting at in my earlier post. the other fixes may be more correct, " right,"  but if I was in your shoes I'd just want that darn leak fixed up for now.   Good luck man, and keep us posted as to the results.  We all need a hail mary every once in a while. :D :thumbs:

you might also try muffler cement if the gap isn't to big

Thanks nbent. I tried another product, i'll be able to fire her up later today if the weather holds and give her a good run and see if she holds. i'll post results either way.  Regardless I had someone who works on tractors come take a look and he didn't think the hole was that bad and said it should be fine to tweak the carb to compensate for the exhaust leak.

Problem solving like this is why these old tractors are fun.  The online community provides so much great info and support.  Let us know the result.  Tinker on...

Well I have it the old college try. I found a product rated to 2,400 degrees for cold weld. I did several thin layers to build it up slowly over the course of several days as suggested. Burned a hole right through it in less than 10 minutes. I've since opened up the carb a bit to compensate for the exhaust leak.

So are you just going to run it as is?

I had someone come take a look who does a lot of work on tractors. He told me to just open the carb a bit to compensate and run it as is and it should be fine.

On a side note I bought a 224 from Titus and will be doing an engine swap soon. I'll put the engine with the hole in it back on the 224 and use that as my backup so in a few more weeks it will get light duty.

While you have that engine off, it might be worth another try with those high temp epoxys or something.

Yeah once I do the swap and am sure the 444 is in good working order I may try to strip down the 224 motor to the block and see if I can get it properly fixed. Probably won't get to that for a while though.
