[Public-List] Exhaust leak...

[Marcelo D. Gentinetta]

I find that the easiest way is to cut the pipe a few inches from the exhaust flange, then remove the 2 bolts that hold the flange to the manifold and remove the flange with attached piece of cut pipe. The flange can then be placed in a vise and the pipe turned free using a pipe wrench. It is much easier than trying to remove the pipe from the flange in tight quarters.

There is a gasket between those two gasket which fails over time. It happens to be where the smoke appears to be emanating. What so far looks like a simple fix, may not be due to access to the four bolts.

Then I took a loose hacksaw blade and sawed parallel to the pipe, from inside toward the outside of the pipe, until I got close to/to the threads, in two spots. I then extended these cuts all the way through the pipe nipple on the section outside the manifold. Then took a punch and collapsed the pipe inward & extracted it.
