Hole in heater box pipe

I have a '73 std beetle. Two small holes have appeared on the bottom of the heater box pipe just at the point it enters the muffler. One hole is maybe

3/16 diameter and the other is half that size. If the flange part on the muffler were straightened (instead of flared), both holes would be 90% covered. I have poked all around the pipe with a small screwdriver and have determined the rest of the metel to be acceptable in that area. The pipes are held together with an asbestos ring (loose fit). a metal washer, and a clamp. I believe this to be the source of exhaust smell when I open the heater vent. Is there a simple easy way to quickly seal this connection? I wondered if a thin metal might be squeezed into place over the holes and clamped?

Bob, There are some Heater Exchanger repair pipes (cheap) that repair just that kind of damage. Either with the muffer removed or the muffler removed, you hacksaw off the bad section off the Heater Exchangers and hammer in these repair pipes. It is also best if you weld them into position, but I guess you could also use some epoxy metal before installation to "glue" them in too. Now if you want a super quick cheap fix that probably won't last use some muffler cement before you use the clamp on the heater exchanger.

Thanks Dave: I didn't know this repair solution was available. I'm guessing the muffler must be removed or at least loosened ? Is this a simple job without removing the engine? After you saw off the heater box end and slide it back into the muffler, do you use clamps to hold it all in place? This looks like the answer to my problem.

Uh Bob, Isn't this why you posted your question....to find possible solutions! :-) Oh and there are more, but some require more work!

I think it is easy to do with the muffler removed. That is about the only time I need to do it and GOOD mufflers seem to go bad in Chicago every 5-6 years on the T1s. Of course you can take off the exchanger too which might be easier for you. Just measure to see if you need to make it a little longer or shorter, hacksaw off the bad section of the heater exchanger and then tap in the repair pipe with a hammer. Then I weld it on and grind down the welds, but you sometimes don't have to! Then reinstall the muffler with the normal clamp and that is it! :-)
