Smoking spark plug wire.

I've never had this happen before. Was running the car parked and hood open and noticed a decent amount of white smoke coming from the engine. If it were black smoke, it would have looked like an engine fire. The engine wasn't overheating or doing anything it wasn't supposed to. Ran fine and never popped a code. Looked closer and observed the white spoke to be coming from the front center spark plug wire. Still had my old plug wires around, so I swapped the wire out, and no more smoke. There was no oil or anything on the newer wire either, and it was firmly seated to both the coil and the plug when I removed it. Thought this was really weird. Any insights as to what was happening?
 


I'm thinking that you're having the very common issue with your valve cover gaskets leaking. The spark plugs are right there under the valve cover at the manifold, so I figure it's probably seeping oil and it's burning on top of the manifold there.

Possible. But once I let the engine cool down (30 mins), and changed the plug wire, I ran it again for 15 minutes or so and saw no smoke. I will take a look at the valve covers just as a precaution tho. Also, my engine (including the valve covers) is about the cleanest 13 year old engine one will ever see outside of a show car.
