White smoke? Usually anti freeze being burnt, or brake fluid. Oil smoke is grey / blue. Water vapour (steam) is white and will condense intantly on something cold to form water droplets, hold something cold and shiny behind the exhaust and see what happens.

 

 

Now, are you sure there's not a communications problem here? Are you definitely saying it's oil inside the cylinder *WHEN YOU UNSCREW AND TOTALLY REMOVE* the spark plug? How much oil? The plug tip looks oily, or what?

 

If it is oil INSIDE the cylinder, or water getting in, it sounds nasty.

could be a leaky rocker cover gasket....oil seeps down into the plug chamber. if the upper of the spark plug and end of the lead has oil on it, it will just be this.... i see it all the time....it can seep into the cylinder too if its bad enough

 

How much are the rocker cover gaskets from you ?

It does look like white water vapour. You are missing the fan shroud, has the car ever overheated? Also when did it first start to smoke? Have you checked the colour of the oil on the dipstick?

 

He's done an N/A to TT swap and it smoked like this when the engine was started aparantly.
