Oil on Plug Threads

Oil on Plug Threads
Hey y'all. Completed a tune up about a week ago, and I noticed many of the plugs I pulled out had some oil on the plug THREADS. There wasn't any oil on the firing end, or in the plug itself, but the threads of the plugs had a little coat of oil on them. Is this really any big deal, and what could be causing this?

dude!!! that's the first sign that your heads are about to blow off the block and take out communications satellites!!!!
nah.. not really..
valve covers are notorious for leaking.. it's inevitable.. sooner or later everyone's leaks, unless they stay on top of it..
the oil pools in the little indentations the plugs do.. they will get some on the threads when you're pulling them out.. If you recall, I bet the business end of your plug socket had traces of oil too, no? a drop or two at the head of the plug, as you screw it out, allows it to smear all down the threads as you extract them..
I guess I may be old school, but I always put a drop of oil on the threads anyway, before I put them in.. and a little dab of dielectric grease on the nipple too.. some use the grease you find at the check-out of the parts store on the threads the clerks are 'sposed to peddle.. same/same (in principle)..

Ive pulled the air cleaner and throttle body off 2 different times now and there is no oil in the intake. Suppose the previous owner did the repair. This truck was VERY well maintained by the previous owner. I got it with 165,000 on it, and the only thing it needed was a u-joint. everything else on the truck was up to spec, and all the fluids were moderately clean, good plugs and wires, etc. The guy took care of it.

95 can you post a pick of your halo LED headlights and what you think about em. Was thinking about putting em in until i saw someone complaining about the plastic melting.
I want MOAR light, oh and a non yellow headlamp :P
ps. sorry to jack the thread just saw seems to be answered oil on threads = small VC leak somewhere. Tighten em down and replace gaskets.
