That is nasty looking. I've never seen that before. Is your car running like crap?

is the car modded? i would say your pcv system is sucking up oil, or your pulling oil in through your valve covers. do you have after market cover? is the baffle on your stockers on? do you see oil in your TB?

yea the car has many bolt ons. see above. the pcv seems to be working well. there is NO oil in the TB but the upper intake looks horrible! i did a compression check on it a little while ago and it took 3 rotations of the engine to pump up to 150 psi. i thought that was pretty high. like the pics show, only a few are sh*** looking the rest have mild residue

when i look down at the valve on a gumed up port, it looks dry with NO residue. the residue stops right after the lower manifold joins the heads.

Is that a GT40/Explorer or a Cobra intake?

Most intakes will pull oil inside the intake..past the filter screen, past the PCV valve and into the intake...in due time it will make it's way into the ports, likely somewhat blowby related.
