I have a 2000 D2 with 100000 miles and on the passenger side of the exhaust there is a leak. I have replaced the gasket from the manifold to the downpipe once before. When I tried to break the nuts loose the entire stud with the nuts came off. Ireplaced the gasket and retighted. It worked great for a couple of months. Then I heard it again. I crawled under and realized that two of the studs were missing. I have reordered all the parts but I was wondering if there is any trick to installing the new studs like using a loctite or something. Any advice would be appreciated. Thank you

 

I do not know of any trick to installing exhaust mainfold studs, I would just use a high temp Loc-Tight.

 

high temp loctite and the proper torque,,,,
