The heat box around the exhaust pipes rattles and is loose at the front end on the pipes. Any reason not to take it to the muffler shop and have it welded back down tight? (IMG:style_emoticons/default/welder.gif)

I had good luck with an old rusty pair by going old school: Brazing up the gaps. (Need a gas-welding smilie!)
I only used them for about 4 years, so I can't say for sure that the low heat did not eventually cause the pipes to crack after I sold that car, but it was fine the whole time I had it. I did have a CO detector in each of my cars during that time... (Get a fresh one every year from a pilot supply.) Oh, and the rattle my car made was actually the cap on the heat shutoff valve over the bypass outlet. It's a bell shaped piece that's held on by three tab-and-slot things. If the tabs work loose, the bell starts to ring... |
