I wasn't saying the plug was new, I mant that it looked new (really clean)

I put the plugs back in the engine, checked for spark on the plug wires (I had spark). I took the car for a little spin and it really is running good, but halfway through I noticed the smoke while sitting at a stop sign.

Came back to the shop, let it idle in the driveway and checked the temps of the header tubes at the head. #'s 3,5,4,6 where in the 400 degree range, #'s 1,2,7 where in the 300-325 range, and # 8 was around 150 degrees. (Not sure what this tells me, just thought I check it)

I pulled the plugs (#8 really clean and wet with oil) and did the compression test after it cooled a bit, and #8 was very low on the compression, around 30 PSI. It was also spitting oil when I was turning it over.

I am going to try the air in the cylinder to listen for leaks on a couple cylinders again, and then start pulling the head.
