Yes it does, Oil that passes by the piston rings will show up on the plugs as a wet oil residue, but oil that comes down through the intake port shocks the plug , sticks to the insulator and forms this white crusty junk, trust me on this one...

A build-up of combustion deposits stemming primarily from the burning of oil and/or fuel additives during normal combustion, normally non-conductive. When heavier deposits are allowed to accumulate over a longer mileage period, they can "mask" the spark, resulting in a plug misfire condition
