In the process of doing a compression test
I pulled one of my plugs and it was covered with oil. I don't know the cylinder number, but it is on the driver's side closest to the radiator. This is the best picture I could get with my camera phone. My digital camera got fuked up last week. Does this mean I blew some ringlands?
I'll post the compression test results when I complete them. Which is the fuel pump fuse? I know it is by the battery, but it is not labeled.

Here is the spark plug that came out of the driver's side closest to the firewall. Look at how much oil is on it.....it is dripping of the plug.

no oil in radiator.
so far these are the compression test results.
1. 125
2. 115
3. 110
4. 125
5. 115
So far compression looks good. I am going back outside to do cylinder number 6.
I spoke to CPrace and they think the valve cover seal and oil rings might have gone and the oil is passing through causing that side of the motor not to fire.

Low compression motors (8.5:1) are going to pressure test at about 120-160. The important thing is the variance between the cylinders.
1-5 arent terrible....which is why I am waiting for the #6 cylinder. CT results can vary based on the amount of oil in the cylinder, and the temp of the cylinders.

Do you realize your kid wrote F*ck in street slang on the refrigerator door? 
You have worse problems than your motor if you kid is writing "***" on the refrigerator door!! I hope a little humor will lighten up your situation there. 
But seriously... talk to your child !!

Gman...honestly...I dont think you have a cracked ring land. In most cases, a cracked ring is going to show no compression or very little compression in the offending cylinder. Yours are relatavely steady accross the board. With a shot of oil, or a hotter motor, you numbers would be a bit higher.
Oil is getting to the cylinder from somewhere..maybe a leak valve stem seal? How did the intake tube to the throttle body look?

Not much in in the intake tube or throttle body. There was some crud in the intake tube around the blue rubber conectors....looked like white dirt. It was not oily, but like a fine dust. Nothing crazy though.
