My Bosch plug wires ($144 llife time waranty) don't seat well on the valve cover and water gets into the spark plug hole and shorts it out till it boils off. It is the one that is not covered by the plastic cover. Other than sealant, what works to keep water out. Does OEM,NGK have the same problem? I took the cap off the see if it was leaking too and it was. I sealed the cap and ruber plug that slides on behind the cap too. I would remove the dist housing to extend the weep hole but I don't have a timing light to reset it.
