friggin exhaust manifold studs!

[Ameer Antar]

Ya, it looked like steel coiled inserts. They were all like that. When I was tightening the studs in, I was a little worried about going too deep as I didn't want to go too far and hit a water passage or something. Each stud seemed to tighten a little differently.. depth-wise. So if the inserts are spinning that means they've come undone, or what? What's the solution? Bigger thread? I don't think the holes in the manifold will handle bigger bolts. What else? Can these things be welded??? Man this is sounding scary!! HELP!!

Do you mean like helicols in each bolt hole?  I have never seen a VW 
head with them.  I would guess it was a repair, but it would be strange 
to have all of them that way.  Both my I-5 (KH, JT) are just aluminum 
threads and my countless VW 4-cylinder heads are all just aluminum.
