Metal shavings in manifold
I have a really dumb question, 
I was wondering if it is necessary to remove the turbo when drilling the manifold for an egt probe. Is it necessary to remove the small metal particles left from drilling and tapping, I mean, most of the shavings are going to be on the outside, but there will be a few small ones left in the manifold, will they damage my turbo? Or should I take the turbo off and suck them out?

Some people say yes and some so no. I don't think it's nessecary to do so. Just dip your bit in greese or some thing to hold onto the shavings and if there are any shavings after drilling use and extendable magnet to get the rest of the shavings out.

Drill the hole while you have the engine running, the exhaust pressure will blow any shaving out. Be sure and wear eye protection as the shavings really fly up fast and hard!

Hopefully the guys who are telling you to leave the turbo on will pitch in for a new turbo if necessary. 
Chances are you'll be fine, but it's still a gamble.
I'd recommend loosening the turbo and placing a piece of cardboard over the turbo's opening. After drilling, start the truck for a couple of seconds to blow the shavings out. Remove the cardboard and button her back up ... easy and safe!
Good luck!

drilling in the manifold
I just put some thick grease on it where i was drilling and went slow, when I got through just used a pencil magnet and ran it down in there a bunch and kept wiping it off. It should deffenitly get all of it and wont affect your turbo at all. And drilling it while running also sounds like it would work good as well just have never tried it but it makes sense it having pressure on it the whole time wouldn't allow anything to enter.

I put grease on the tap. I would make a couple of turns then remove it and clean off the grease/metal. I then re greased it and went a little farther.
An old fabricator showed me that trick many years ago.
You can't go all the way with it in one run. You MUST go a little at a time and clean it off to keep the buildup down. Worked like a champ on mine and a friends. NO metal got into the manifold.

Oh, forgot to mention, I did it with the drill bit too. You must go slow enough not to get it hot enough to melt the grease. You must also stop and clean it off just like with the tap.

This may say more about my skills than the method?

Ok, I did it, I drilled it with the engine running and tapped it with grease. I'll let you know if my turbo blows up. Although I'm sure it won't 
.
So far so good.
