[QUOTE="05 Roush, post: 1370779, member: 10919"] I'm having similar problems with fitment. As luck would have it I know it's happening when I lose a pound or two of boost. At 23K miles I pulled all the plugs and noticed plugs 3 and 6 (not 2 and 7 like I said before. Had the motor reversed) were scored all the way up the threads, indicating sparkplug blowby. You can torque up the threads as tight as you want and they will still leak/get loose. I've come to the conclusion that I have to retorque the plugs every 3-5K miles. Is there an anti-seize compound that also seals threads? :read: EDIT: Oh, and I retorque after getting the block extremely hot. [/QUOTE]
