sparkplug wires
I have a 97 F150 4.6 , that every few months I have to replace the # 4 and sometimes the #2 sparkplug due to moisture down in the well causing the plug wire to look for a ground which in turn misses up the plug , the plug has the black lines down the side from the arking going on in there . I have heard there is a certain type of plug wire that will correct this problem . Does anyone know if such an animal exist ?
Thanks Jeff

Motorcraft wires are about the best. You need to find out where the mosture is coming from. Sweating a/c line dripping into the plug pocket? Also check for a small antifreeze leak where the heater hoses connect above the #4 cyl.

I heard this was a problem with the 4.6 and that there was a certain set of wires that would correct this , but i will check for any leaks to see if it more than just condensation causing it .

Same problem
Hey Jeff
I have similar problems with my 4.6. Lexman knows his stuff, I deffinately use motorcraft plugs and wires only. They are the only ones that seem to last. It seems #2 and #4 plugs are a trend too.
A trick I learned for moisture is to put light coats of mineral oil or contact grease on the outside of the plug connectors to create a better seal on the plug holes. Niether of these will dry-rot the rubber boots. I hope this helps

Motorcraft wires are the way to go. Coating the inside of the boot with dielectric grease, you can get it at any auto store, is also a must. Like someone else already said, look at the heater hose right above #4 cyl. for a coolant leak. It probaly has a spring clamp on it. Remove that clamp and put on a regular clamp. That should take care of your problem, good luck.

Thanks Eric for your reply ,sounds like motorcraft wires are the way to go and also will use the grease trick to try to insulate from the moisture . It is a weird proplem , since it is the 2 and 4 plug only .
Thanks Jeff
