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 !!!!!!!!!

The problem is the gasket, not the valve covers. Replacing with a new gasket fixes the problem permanently. Has nothing to do with the valve covers themselves.

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.

Replace the spark plugs and seals and to be super safe might as well replace the COP as well. That way the you wont have problems for another 50+ thousands miles without problems. I had the same problem with my car every time it rained. If you do not then the catalytic converters may get damaged...Dont risk it.

This seems to be a case of "process elimination": they dont know WTF is wrong withe car, but start changing parts and HOPE it fixes the problem, if not then keep replacing parts until it does fix the problem...the nightmare of all modern computerized vehicles. All this technology available and mechanics still cant pinpoint wtf is wrong with a car. Now I bet you try to do the same for an airliner and the problem is pinpointed in minutes with the same technology.

Hi, I got a letter from ford/lincoln. Providing extended warranty coverage under customer satisfaction programs 07m07 and 07n09. Extending the warranty of ignition coil to a total of 10 years. If thats the 1 your asking about. Check under them programs for more details.

the "plastic" valve covers don't warp if installed correctly,they are made of carbon fiber reinforced resin ,yes a type of plastic but not realy.EVERY car with plugs going into the valve covers leak regardless of the material used to make them .the 'plastic' is used on the intake ,cooling system,valve covers and a bunch of stuff you will never know about in the car .the reason for this is because it has better noise damping ,more consistent temperature control ,it is lighter and yes it is cheaper to manufacture which means you spend less on the car.the use of 'plastics' on cars saves a butt load of fuel every year just through the weight savings.
ford was not the first to use plug through head design (not even the infamous HEMI of yesteryear was the first ,but they leaked to!) the dodge 2.4 has an aluminum valve cover and they leak like a sieve because aluminum expands and contracts at an unbelievable rate where as 'plastic' does not.hondas are notorious for this to.
your car with the 3.9 isn't even realy a ford ,it's a jaguar and anyone that knows cars knows jags are money sucking cars that rarely ,if ever, run proper ,your blaming the wrong company.
i guess if you don't like fords 'better idea' then go buy a Cadillac cts (same class of car) or a 300m and you can experience REAL problems and you will look back at how cheap to maintain and repair your ls was (caddy cts 3.6 40k miles ,timing replacement after they changed oil and used conventional oil instead of full synthetic....$3.500)
the trick to owning any luxo car (cept for the old Lincoln town car) is the same as owning a corvette....buy 2 so you got one to drive while the other is in the shop!luxo cars are only good for about the same time as there warrantee then they start to degrade fast,people who buy these cars new trade them in every year or two so why bother with longevity?ALL car manufacturers do the same, even imports.
if you want durability and cheap repair bills buy a taurus,you bought a high dollar status symbol for a car get used to paying to keep it up.

Your post makes a lot of sense. I have a 04 Lincoln LS, and a 99 Ford Taurus. In my case the way I see it. You are right, I have had my Taurus for 10 years this December 2012. Rides like a champ. Now as for my Lincoln, which I have had since Jan. 2008. A whole different story.
