I have read, read and re-read the forums and TMs. Clinto's write up was well done! I have learned alot and it is my turn to pay the favors forward. The PB Blaster has been doing it's magic. I start tear down today and will accompany with pics.
BOTH. The bolts on the top of the turbo suck! MORE PB! Gotta get the kid ready and gotta head off to work. The major stuff comes off tomorrow and will have pics.
Worked on it for 5 hours today. Removed the turbo, intake and exhaust manifold, thermostat housing. The bolts that connect the turbo to the exhaust manifold sucked. Broke one bolt completely. The front/right bolt is impossible to get at. The nut was stripped. Had to remove the manifold/turbo as a whole and will separate later. The gaskets were roached. I did find that the bolts that hold the intake can unscrew if the nut gets stuck. Got me worried that i was stripping something out. Pics to come when I get to the heads. 7 hours of work at this point, just me doing the work.

Turbo bolts: Same here, that's why you can see the turbo still bolted to my manifold in my thread. Go ahead and replace all 4 and consider liberally coating with anti-seize.
Intake studs & buts: Same here. I had a few nuts that were so tight, they caused the stud to unscrew. I tried to source replacements (even from the local Hercules dealer, via a John Deere dealer) and no one had the right size and pitches. A specialty fastener company will probably have them. I can't remember of those studs go into a water jacket, if they do, use RTV sealer.

I've had the best luck using loctite to seal studs into water jackets. Especially if the threads are a bit worn in the block/ head.

And make sure that when you are going back together ,tighten the intake manifold evenly otherwise you may crack an ear Some guy named Murphy loves my shop sometimes....

To remove the exhaust manifold and turbo together. The water jacket has to be removed first. There is no other way than this. First remove all but 2 top nuts on the exhaust manifold. I left a few threads on the 2 top nuts to have enough to pull the exhaust manifold as far from the head as possible but enough to hold it on. Then remove the water jacket by rolling it up then pulling it out. I was surprised at how many nuts were loose!
Head Gaskets/Freeze Plugs....It begins
