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

i believe the pipes are stainless too - a magnet should not stick - some though do have steel muffler flanges.
i assume high heat is hard on stainless ?? brad - how frequent would you say this is ?? would capping one end off and filling them with water be a good enough test ?? jim -- |

Frequency? I pitched a couple before I cut these open but I have probably sold 50 used pair since they became available in the 70's. Any method including water should work but there is a possibility of a tiny crack not showing with air or water. I don't have set test procedure for the air pressure, we use 10 psi, the time period until the air bleeds off mostly depends how good the test plugs work. Be careful not to aim the expanding rubber plug (hardware store item) at anything during test! Brad |
