Hi all,
It looks like the top section and the bottom section of OEM heat exchanges are simply crimped at the seams. Does anyone know if it is feasible to un-crimp them, take them apart and later on re-crimp them? If so, then I'll have a go at using the spare set of heat exchangers I have (with some modifications) for the heat exchangers on my to-be-built exhaust for my 2.8L Corvair transplant. Thanks all, Dave Oz |

Govm'nt meddling again....
I wonder if you could get the fresh air fan to work well enough to pass the test. How do they check for that anyway? Why do you want to take them apart? are there holes? You could wrap it with that stuff "as seen on TV" They make a high temp version. Can't remember the damn name tho. You dip the roll in water and wrap whatever you want to wrap and it cures hard as a brick. I used some on my HE. 40000 miles and it is still wrapped enough to blow super hot air. Good Luck. |

I have to take them apart to be able to either: 1. Weld 3 inlet tubes from the three exhaust outlets into place on the existing tubing, or 2. As above and add complete new exhaust tubing if the current tubing is beyond further use. Don't think I can do either without 'peeling the banana'. Dave |

Dave I guess it needs to work for you if that's the regulations,hair dryers are useless and draw to much current ...ask me how I know (IMG:style_emoticons/default/dry.gif) . I have deleted my heater control and just have a switch to run the blower on full speed ,demists the screen fine,I proved you don't need warm air,my Audi for instance will demist with the AC on for a short time. I think it would depend on your climate which I would say would be colder than where I live in NZ. |
