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

Since the weather is starting to cool off I thought I would give this tread a bump. I am getting ready for my last swap meet of the season in Cincy this weekend and going through some SSI exchangers. One out of 5 that I have leaks. I just do a simple water test. I plug the muffler end and fill the tubes with water and let them sit for 30min. doesn't take long for water to find a pin hole or crack and start to seep out. The exchanger I have that is leaking water looks great, no dents, but one of the tabs has been repaired. Be careful when buying SSI exchangers ask the seller to do a simple water test to verify they don't leak. I will also to Brad's air pressure test on the ones that pass my water test just to make 100% sure they are fine. |
