03 Expedition Water around the spark plugs!
 

I have an 03 expedition and I keep getting water in the cylinder 6, 7, and 8. It is blowing my coil packs and destroying my plugs. Where is it coming from and how do I stop it? The dealer told me to stop parking nose down on hills! WTH!!! Really? So much for built ford tough. What do people do in San fransico? Sorry honey we have to move, house is on the wrong side of the street for the truck. Seriously I need my truck to stop going into the shop monthly, can anyone help?

If water is getting on your plugs use dielectric grease around spark plug boots, that should solve your problems!

Not sure if this applies directly but its the same problem.....
