a leaking valve cover gasket is the only way that i could get oil in my plug holes right? what are the chances of both valve covers leaking....i have oil in plug holes for 4 and 8....ford dealership says that is the only thing that could cause it, but i wanted to see what you guys think...

That is the only place that oil would come out of the top of the engine. Unless you deleted your pcv system and just put breathers in.

ok thanks, thats what i thought, just found it strange that the valve covers would suddenly BOTH leak after an intake swap...coincidences at their finest lol

Check and make sure your pcv is working. You might have to much crank case presure and its pushing out there. I doubt it but its possible. I had it push oil out of my front crank seal until i fixed my pcv system.

how would i check that? just let it run and see if theres oil coming out? the car is at my dads house currently so i cant go look at it right now

Im having the same problem and it is my valve cover seal.

Just fixed this on my friends 98 Cobra. It was the valve cover seal. Not to hard to fix. Just need a jack to slightly raise the engine to get the valve covers off...you just need a day.
