Changed plugs and tubes - now smoke?

[reiver]

I changed the tubes, both o-rings are new on each tube, and got the exact same spark plugs. I have an almost rich smell with smoke coming out of the tailpipe. Some of the plugs were in pretty bad condition and the driver side had 2 leaking, with 1 leaking on the passenger. This was dripping on my cats/exhaust and causing smoke (not out of the tailpipe) anytime I went over 5500-6000 rpms.

I thought I'd take care of that, replaced the tubes, o-rings (used the sucker OEM o-ring grease that comes in a $50 tube), and plugs. The only problem I ran into was on one of the last ignition coils. I overtorqued (I think the screw was already weak, because I didn't torque as much as the rest) one of the top screws/bolts that are 5mm allen on the center coil on the passenger side. It seemed like it was still firmly in place, so decided to give it a start twice. Both times it smoked what looked like white smoke in my hanglight (took longer than I expected) out the tailpipe.

The only other thing was that Dew was in full effect, so ambient moisture is high. Did I not tighten one of the spark plugs enough? or is a tube not fully sealed? I left it up on stands for the night and the car is at a slight angle with the rear being lower due to a combo of my driveway being at a slight angle + the heavy duty stands in the rear are a notch or two lower due to the much bigger gaps in the stands and it barely not being high enough for the next notch due to my $300 jack not fully raising. Not buying Craftsman again.
