Don't be too concerned with shavings, other than wear goggles to keep them out of your eyes while you drill. I just drilled, tapped, and installed adapter & sensor. Any shavings will blow out the turbo.
And yes, run the tap in, then back out. Go in a little further, then back out. Repeat until you get to the depth you need. Might not need to go all the way in, so when you get about half way, back the tap out and trial fit the adapter. Also, use copious amounts of lube. I just kept it wet with WD-40, but there is special tap lube that is probably better...
I too was aprehensive to drill and tap for the pyro probe. For me, this turned out to be the easiest part of the install. Like Joe said, do not run the tap all the way in and test fit the fitting once you get past the halfway point on the tap. I did this 3 times until the fitting started tightening up on the last thread. If you run the tap all the way in, you could end up with a loose fitting that will never tighten.(Tapered threads)
I ran the 'R' bit dry at low speed, after drilling a 1/4" pilot hole. I turned the tap dry. Then I went in with a magnet and shop vac. Then I fired up the truck and let it idle a minute or so to blow out anything I might have missed. (Maybe overkill, but peace of mind for me). The whole drill, tap,clean, and install probe part took less than 30 minutes. Spend money on a good bit and tap. Wear goggles.
I just installed the EV2's I bought from clay. Thanks to this forum and weekendwarriorfs32(Nick) that helped me out. I couldn't have done it with out him. It was not that bad. I would say the EGT probe was the hardest but thankfully I had Nick to help. Now that they are in I love them. Just take you time with wiring the gauges I reversed the wires on the boost gauge. We got it figured out and they look great.
I put the tap in my drill (did not drill a pilot hole), tapped the hole with no problem, and did not worry at all about the shavings. That was 25,000 miles ago and I had no problems.

yep, I just stuck the tap in the chuck and drilled into the soft cast iron with it. I showed my master mechanic friend all the precautions others have stated, and he was like "screw all that, just tap it and forget it!"
What kind of drill do you have?? I've broken more than one tap by hand with a pre-drilled hole, so I'm amazed that you can drill with one. Is this some kind of special tap that doesn't need a pilot hole??
I re-read 18 Roland, and I'm still corn-fused. LOL

Air-powered impact drill. Regular tap from Sears. I couldn't work without air tools now! I'm spoiled.
I used a variable speed cordless drill to drive the tap (his idea) when we did the pyro probe on my friend's 6.0 manifold, but we did drill a pilot hole first.
