Are you saying spark plugs?
Leaky valve cover gaskets.

Car: yep

Engine: uhuh

Transmission: sure does

This is not proven, but just my thoughts..

I see oil on the threads of new and old motors alike, with no valve cover leaks.

I think that the oil from the cylinders that comes by the rings (for lubrication purposes) gets forced into the bottom of the plugs.

What isn't burned creeps up the threads just like WD40 would.

Its not a problem.
