Alert me when someone posts in this thread:

ADVICE Needed: Please comment 2.3L exhaust studs. I sort of "buried" this as a self-response to earlier thread, but I didn't receive any feedback, so here goes with an updated version.

I succeeded in removing the broken #7 stud. I was learning, I went slow, and I took way longer than a professional could afford to do. Holes were all nicely centered ! Will report on technique separately.

1) Question one - Should I replace the LONG studs at #1 and #7 with short ones ?? Studs # 3 and #5 are also long, but are used to hold on the heat shield. I have read that they don't break as often as the end ones, so I am thinking of just replacing all except #3 and #5 with short studs.

2) Question two - I have a set of stainless studs on the way from Genuine SAAB, and I would sooner use these EXCEPT that they are all "short" - so I would have to devise a way to locate the heat shield. Anyone done this ? I will not mix the plain and stainless studs.

3) Should I use any Loctite or anti-seize on the studs for the exhaust manifold ? I see most use anti-seize on the studs for the Turbo - recommendations ?

4) Which SIDE of the Turbo - manifold gasket goes UP ? The "outy" or the "inny" (convex dimple UP or concave UP) ? AND can one use exhaust manifold studs in the Turbo flange ??

Thanks in advance !
