I keep having to replace coils. Right now Autozone says the #7 is bad. The Dealer rate is straining my limited budget. Ready to dive in and do it myself. I also believe that changing the valve cover gaskets to the latest bulletin spec will stop or reduce coil problems from oil seepage. Anyone else have thoughts on that.
You are right about the valve cover gaskets. The gaskets fail and oil fills the sparkplug wells with oil. The rubber boots get oil soaked causing the spark to short out which causes the coils to go bad. The only fix is to replace the gaskets.
I replaced the gaskets and the COPS(coil on plugs) over a year ago, and haven't had anymore problems with the coils. I bought the valve cover gaskets from the local Ford-Lincoln dealer. Lincoln up graded the gaskets in late 2002, and from what I have heard, they are the best you can buy.. I bought all 8 COPS on a popular online auction from a seller with excellent feedback, and saved quite a bit of money. You should replace any COP that has oil on it. I replaced all of them so I wouldn't have to do it again! It took about an hour to install the gaskets and COPS.Make sure that you get all of the oil out of the sparkplug wells. I also replaced the sparkplugs.
Don, you could buy an repair manual at your local auto parts store, if you can find one. Auto Zone.com has the repair guide on their website. Just enter your vehicle info, then under intermediate click on your repair guide. Then go to engine mechanical, Then click on valve covers. The instructions are easy to understand. Make sure when you remove the old gaskets, you don't deform the sealing surfaces. Be careful . After you get the valve covers back on go to engine electrical, distributorless Ignition system, Ignition coils and follow the instructions. Don't get in a hurry and you should have no problems. Jim

Thank you, windryder, where do I find the best directions to do the gaskets and COPS? I understand the drivers side (cyl 1,3,5,7) are the worst.
