Waterproof Ignition
Everytime i go offroad or wash my engine water seems to make it way down into the spark plug holes and causes a bad miss iv'e tried 3 brands of wires (motorcraft, taylor and bosch) no better when it happens i pull the wires blow the holes out and put some more die-electric grease on the boot and its good to go. It always seem to be cylinders 4,5,6 front 3 on left side. Anyone have a fix because my next fix will be silicone around the top of the boot.

Well, if you have a distribulor, silcone the cap shut and add a vacume line in the cap. unless you are dumping gallons of water directly on the plugs, the dielectric should not be washing away.
Or you can finish the engine wash with a nice coat of WD40.

Other than using silicon around the boots, I don't know of any cure for this problem.
ReAX, FYI, all 97-up trucks use a DIS ignition ( Distributorless Ignition System) They use a crank/cam sensor for the ignition pick-up and have either coil packs Early 4.6L or COP's (Coil On Plug) systems.
