yeah I don't think they would try so hard to con you as to try to produce fake smoke but at the same time I don't see how a smoke test could be mandatory. They do seem like they really push the Authority on what they consider an acceptable repair.Connected leaf blower to exhaust pipe to pressurize exhaust system, and found NO leaks when spraying soapy water around manifold.
I definitely saw smoke coming out at the shop. It was a cold engine so I see no way they could make fake smoke. I saw this test with my own eyes. I feel it was a legitimate test. But neither I nor they could tell exactly where it was.
Now even if the manifold is removed I do not know if anyone can find where the mystery leak is in order to weld it.
Other than visual inspection is there any way to find the leak after the manifold is removed?
The stick in the one photo points to the stock weld area that the smoke appeared to be coming from.
I think you are right Bill. I am so old I only know cast iron headers. These are smooth, not bumpy like old cast iron manifolds."Stock weld"??? That doesn't sound like an iron part to me, you avoid welding cast-iron as much as possible; it is not a normal manufacturing process. Looking at the pictures, I think it is a steel (or SS) fabrication; would be much easier to repair.
Unfortunately not.Can you get a mig welder tip to the crack?
It kills me now as well to have to hire someone to do work for me!Unfortunately not.
After investigating all the putty, wrap, epoxy, etc products available on the market today, non are good enough for a good permanent repair on a manifold IMHO.
I was hoping something new had been devloped since I was in the field years ago. But non of the reviews proved that to me. Most products did well on tailpipes and mufflers but not on super hot manifolds.
A local shop will R&R the manifold and have it welded Monday April 5. My age prevents me from doing it myself.
Thanks to all of you for helping with this decision.
