It's a 'normal' thread on the V6, anti-clock to undo. They just seem to go fiercely tight on these later engines for some reason. Never had problems with the older 12V motors myself, but the 166.....
I applaud buying the right tool for the job, but a honking great rattle gun I'd only use once or twice is maybe a bit too much for me compared to a £6 nut and a 20p drill bit. If I was more into repairs now (as I used to be a few years back) then I'd get one. As it is, my 1/2" Snap-On rattle gun does most of what I need it to.
You may find your compressor short of puff with a big gun though - it's not about the pressure so much as the delivery rate. All you can do is try it and see how it goes.
If you do end up having to resort to the drill, just make sure you drill into the flat section of the nut away from the crank and you'll do no harm. Worst case if you are a tad enthusiastic is you might put a dimple in the washer - no problem if you do. IIRC, I started out with a 3mm, then a 5mm, then split it with a chisel. Painless.
Best of luck with the job though - hope the gun does the trick for you.
