Yet Another Exhaust Stud Dilemma
My 3.0 rebuild went fine, then a noise from right side exhaust. I checked the head studs, they are tight. Checked the exhaust studs and the barrel nut on #6 turns and turns with ease in both directions but will not come out. Because it turns but will not come out, I fear the stud is pulled from the head. Am I thinking correctly here? How do I get the barrel nut off? Right now, I don't think I can remove the exchangers/muffler, etc. until this nut is off. Or can I? Any advise? Also, I'm wondering what damage (if any) will be caused by driving with one exhaust stud busted? It sounds like an old VW and is embarrasing, but sure does go like stink! Can I get by driving it with a bag over my head (figuratively, of course) until next winter when I figure out the stud removal process...?

you have to find a way to get some pressure on the nut from behind, as you try to remove it. the best way i can think of to get it rolling is to remove all the other nuts and then pull on the exchanger. the right exchanger attaches to the crossover pipe, so that should be separated too. once it is worked off a bit, a screwdriver can be slipped in for better leverage.

Mr. Walker,
I'm honored. Thanks for the advice. I see you're heading for 5,000 posts! But what if I drive it in the current condition. It's loud but fun. Will it damage anything? Thanks again. |

I never did drive it that way on any of my cars. But my guess is:
1. you won't pass smog 2. repeated vibration will damage your exhaust surface on that head. This is particularly bad on the Porsche because you "may" have to surface all the heads exhaust flange to make it even. I secretly think a little copper spray would work there, but ... 3. Sounds like a volkswagen, and gives us all Porsche owners a bad name. 4. Exhaust leak on one cylicder cannot be good for engine power if you take into account that many exhaust runners are length-matched (and tuned) for maximum power. Leaking on one runner will throw that off. Anyway, my $0.02.
