Well the new gaskets are installed - will see how long they last. I still don't trust plastic (composite) valve covers. Alot of manufacturers use cast aluminum valve covers or at least metal, especially when the spark plug is in the middle of the cover. By the way my LS is a 2000 V8 3.9 liter. Do you own a LS or just work on them?

I bought one in October 99 and kept it 6 years. I also belong to a club of LS owners.

What is this letter that you got from Lincoln? My 2004 LS just had to have a coil replaced and now it looks like maybe I shouldn't have had to pay for it. Please let me know because we are now starting to experience more problems with it.

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.
