No oil with overnight rest. Also you can change it with the spark plugs still in using Pedro's trick with the 7$ marine plug.(trim the edge to be as one cylinder).
I suggest cleaning the inside of the tube and the tool with goo gone or similar cleaner or even Acetone. It really improves the grip and friction of the tool and reducing the chance that you break a tube since you need tighten less.
To put them back. I put back one screw from the coil packs and used a socket laying on its side covering the tube, prying against both a 10mm long key to pry push them in. With this method I could change a bank in 10 mins. Versus the 1 hour it took me on the other bank
. Also, remember to pre-lubricate with engine oil and clean the carbon deposits on the valve cover.
Good luck!
