Looks like Cylinder 5 took a crap, I pulled the spark plug and it had coolant and oil on it. Looks like head gasket job, any suggestions on the easiest way to get the job done?

Umm... Higher numbers is better. Looks like you're low across the board EXCEPT for cylinder #5. I think your rings are very worn out if all your numbers are that low. Looks like it's more than a head gasket. Looks like it's a full rebuild.

If he found coolant and oil on the plug with the highest reading I think the coolant and oil sealed the rings more then usual which gave the higher reading. I would say check the head gaskets first, worst comes to worst he's already a step ahead if he decides to rebuild the motor.
