I have a small leak where the muffler flange bolts to the heat exchanger flange. I put in a new gasket, but still a leak. The muffler flange looks slightly bent at the 2 outer bolts. I don't want to hammer this thing too much and break the ears off. Can I use some type of sealant here??

I use red RTV (about the only thing it is good for) and two gaskets to get a good seal. Seems to work good.

Heat it up with a torch and bend it with a pair of channel locks. RTV is a band aid.

Or cut it off and weld a new flange on. Muff shops are cheap if you don't have the equipment. Tell them it's a VW, you get 50% off the Porsche price.

Fix it once and do it right and you'll never look back. . .

I agree, with one glaring exception. Instead of channel locks, use a crescent wrench. That way, the jaws are in a fixed position and you won't be struggling to keep 'em tight.
