Water on spark splugs & sealing them up

[vica153]

It seems like everytime I check my spark plugs there is some water build up in the hole. Atleast one time it was causing some misfiring. The upward angle of the hole and less than perfect fitting seals on the plug wire means water can get it and it can't get out.

I use lots of dielectric grease on the plugs and that keeps misfiring at bay for a while, but I think I may try using a little bit of high temp silicone around the rim of the plug hole.

Has anyone here tried this before?

from my build thread
"the quality difference both in feel and fit and finish was remarkable. while the BA's seem to even allow water to get into the spark plug hole, the NGK's are a nice tight, solid fit with a very positive snap as you put them in. I got the NGK's from autopartswarehouse.com for 36.95+ shipping which was the cheapest I could find. gotta pay for the good stuff I guess.

major quality difference

I'm using a set of the Belden Lifetime warranty wires from napa. They seem like pretty good quality, snap on nicely, and 1-2 of them seal up the holes pretty well, but the others don't.

As dumb as it sounds, nothing compares to the quality of NGK wires.

Both Subarus I drive have them installed.

I had a set of Autolite wires on my Forester for less than a year and they started arcing. No signs of wear, just genuine junk.

A good set of wire will keep water out of the holes. Both the NGK's I have, and the Magnecor's kept the water out.

NGK, never have had a problem.

Well once, but never leaking.
