Replying to: plogman (Oct 08, 2009 7:22 am) Your coils are getting soaked with oil because they are located in the center of the plastic valve cover. This plastic (composite) valve cover has o-ring type seals around each spark plug hole - this hole fills with oil because the plastic heats up and does not exert enough pressure to maintain the proper seal !! FORD HAS A BETTER IDEA. I think that was their slogan - what a joke. There needs to be a cast aluminum valve cover like the Japan made cars. I like the car but I can't trust it on long trips because of this engineering flaw !!!!!!!!! Replies to this message: akirby (Oct 09, 2009 6:17 am) toomanyfumes (Oct 10, 2009 4:36 am)

Replying to: akirby (Oct 09, 2009 6:17 am) On the 2004 there might not be a valve cover gasket leak. I think by then they used a different gasket that lasts longer. Sometime the coils will just fail.
