I just picked up the rig in my sig. It's got a blown out gasket between the manifold and the twin pipes. It's that funky little oval shaped gasket with the three bolt holes in it.

Now on to my problem. The reason the gasket blew out is my manifold is missing one of the studs and one of the others is missing the nut. So my whole exhaust is held onto the manifold by one nut!!

Does anyone know off the top of their head what the stud thread pitch and diameter is? And is it the same where it goes into the manifold as it is where the nut screws on?

I've got the gasket and all tools ready, I just need to know what nut and bolt to pick up (no, I'm not replacing the stud. The Zuk wannabe will die some horrible death before that bolt ever needs to come out again).


I use the beastie for my work (road side assistance), and end up driving it about 1,500 miles a week on mixed traffic. Everything from idling in 1st to foot on the floor trying not to get run over at 80+mph on the freeway. Needless to say, a small leak at the front main seal plus the exhaust leaking right there could equal an engine fire!! I've got a little time today to get it fixed, just have no idea what size bolt and nut I need.

And no, I can't seem to get the one remaining nut off. No matter what wrench I put on there, it's like it's the wrong size. LOL
