The temp is running at 200 plus or minus a needle width or two. This just started to show on the temp gauge in the last week or so.
This is abnormal for the truck cause it usually runs at like 180/185 and the high is 200, it sits at 200 for a bit and jumps back down to 180.

 

go back and YANK IT OFF, it takes 10 minutes tops... there is at least 1 small passage that needs to be clear and I'll bet it's blocked. while you have it off take a good look down into the intake manifold and see if you can see any oil pooling on the bottom of the intake, use a mirror & flashlight to check all 4 corners. if there is then your plenum gasket is leaking.

when you go to put it back on, if you dont have a torque wrench, snug the bolts good but dont go gorilla nuts on it. the torque spec is something like 11~13 ft lbs IIRC and that is not much.

everyone here will tell you to yank it off, it's simple and will make your life alot easier.

 

I guess being lazy didn't cut it this time. Thanks Steve.
