Are you sure it's not the air conditioner line above it? It may start to sweat and drip onto the cap. Same thing happened to my dads.

i don't think that is it but it could be cause it only happens when it rains but that is somthin i will check out


thanks pig

Its a TSB, the AC line runs right abouve the dist. and drips into the dist corroding it, happens most on long drives with the AC on. To fix it just put some wire loom over the ac line to keep it from dripping right on teh dist, about a foot long piece, so it drips out either side around the dist.

why only when it rains though

maybe more humidity in the air makes it worse.
