I posted this last year, heating season is here again. These are big cracks, a tiny one you would not be able to hear would still be dangerous. These are not accident damaged. If you have a set on your car, grab the carbon monoxide detector from home and take a ride with the heat on and windows rolled up. There is a detector used in small aircraft also available. The last photo is how we now test for leaks using air pressure. Brad

Sounds like we should see if someone is willing to make new SSHE's even though the price would be PRICEY.
Racer Chris at Tangerine? ALL Stainless? Something to consider. Life is good, but CO is bad. I don't use heat, but this scared me good. I checked mine when off the car last spring by filling them up with water and looking for leaks pipe by pipe, but it was all good, still, no fun to gas oneself unknowingly. John |

John I'm pretty sure they are available new from Mittlemotor - pretty but pricey. http://www.mittelmotor.de/webshop/englisch/mm.htm $1,200 Attached image(s) |

I had a 1.7 set of SSIs on my 914 and after many attempts at tightening up what I thought was an exhaust leak at the head found out the pipe has a crack at the first bend inside the clamshell (noticed this when I was looking at it at night and saw fire shooting out).
Removed that set to install a 2.0 set I have had for years and years. On the driver side unit, noticed there was a crack at the point where the pipe entered the clamshell which was caused by stress from the other end not quite lining up to the exhaust hanger. Had to be pulled over about 1/4" or so. Over time, the crack formed. (IMG:style_emoticons/default/sad.gif) OK... on to my final set of 2.0 exchangers. No visible cracks but one of the pipes can be twisted slightly back and forth so that is also useless (IMG:style_emoticons/default/dry.gif) Three sets of SSI exchangers... all three sets have at least one side with issues. I was hoping to get some heat into my 914. Think I will block off the driver side and just hook up the passenger side. Then will see about having the bad exchangers repaired (IMG:style_emoticons/default/welder.gif) (IMG:style_emoticons/default/driving.gif) |
