If you see droplets in one cylinder only, that's a water leak. You have fairly new exhaust and a mild cam, so it's probably an intake leak or a head gasket leak.

Change plugs to AC Delco. WOW what a difference. A complete different reading. Plugs look more a like. Still doing some testing.
RATMAN, that is one of the best site on plug readings. All these years I have been reading plugs wrong.
