Diagnoses of these spark plugs 
thats the #4 plug, half of it is white the other half is burnt
does that mean anything ? or is that normal
the #2 plug looked like that but not as bad.
the plugs are a few months old.

Is it possible to get a clear close up?
From the description, it seems to be oil deposits.
Check the rings (compression test/leak down test), valve seals and guides.
Most likely source of oil.
