Christian,
If you are working on the turbo it's too bad you decided to pull it, since you can just unbolt the turbo from the exh manifold! In any case, it's not all bad, since you should replace all the gaskets there anyway if you are replacing the turbo. I encountered similar problems a week or two ago when I was trying to remove and replace my exhaust gasket manifold and exh manifold to turbo gasket (if you are taking the turbo off, you will want to replace both of these gaskets). A few tips:
- buy a can of PB Blaster or Liquid Wrench, drench every fastener you want to remove with it and let it sit overnight. I can't imagine doing this job without it!
- Get new exhaust studs from the dealer; prices are outrageous, but they fit correctly, the aftermarket versions from Eeuroparts may work but are shorter. Get copper locknuts, the ones from Eeuroparts seem fine.
- The stripped bolt on the tranny is a tough one, there is not much room there, but perhaps you can file two flat edges on the head of the bolt and grab it with vice grips? once you get it broken loose it should come out easily. Also, the threads for the bolt *might* be accessible from the other end of where the bracket mounts. If so, spray some penetrating oil from the back, this might help loosen it once you're able to grab it.
- The second stud from the top also broke off on my cylinder head. I was worried I would have to take the head off to fix it, but I managed to fix it. My stud was broken off *inside* the head, so I couldn't file'n'grab or weld a nut on the exposed stud (others also suggest heat for an exposed stud). I carefully used a center punch and a Craftsman Dremel Tool to drill a hold in the center of the stud, then a No.2 Craftsman EZ Out to tap in and get it out. I also soaked it in PB Blaster for a couple days while I tried a bunch of other ways to get it out. For me, this seemed to work the best. Once the EZ out was in there, it came right out. The combination of heat and agitation from teh Dremel really helped I think. Also, get a good mirror so you can see!
- I had a Helicoil kit ready just in case, but I'm telling you, that stud is a bear to drill out. I advise at least 2 or 3 drill bits of increasing size to make it easier. (I think the Helicoil kit asks for a 21/64 bit).
Well, that's about all. It took me a while to get the courage up to drill into the head, but in retrospect, if I had used a Dremel it would have taken only a couple of days (at least 1 day of soaking in penetrating oil). Good luck, and email if you have questions! Best,
Ram
