Exhaust leak at nut
Noticed today that exhaust is coming out from under the nut ( between the pipe and nut ) that connects the manifold to the pipe. The nut is tight. What can I do?

Re: Exhaust leak at nut
There are some repro brass nuts that have been available off and on over the years that aren’t quite machined just right. The threads and/or clearance inside isn’t quite deep enough and the pipe flange doesn’t get tight against the manifold.
If this is the case, you need a better quality exhaust nut.

It turns out the flare at the end of the pipe was broken off! Ordered a new pipe from Lang’s.

Re: Exhaust leak at nut
Jonathan, that sometimes happens when the flange does not contact the manifold correctly, and the nut is done up tightly to close the gap. This puts stress on both the pipe flange and the manifold. The flange needs to sit neatly on the manifold before the nut is done up.

I use 0000 steel wool as packing inside nut. Seals very well.
