Take a look around the outlet of the tailpipe.
IT should be dark color - similar to "Kingsford charcoal" but not greasy - if greasy- the oil is getting sucked back into the motor - more than likely from the PCV valve.
Another area to check would be when you find the MAP sensor - mine is located here...
But also check the BREATHER hose, that comes off the valve cover to the Air Filter - it too uses a "sponge" to mop up and hold oil - but the little "cup" it rests in - inside the airbox itself - under the air filter media - also can get plugged.
IF this hose gets plugged, the only way the engine can get rid of any vapors is thru the PCV valve and can force leaks to appear around the valve cover and spark plugs are in a trough inside this cover - which can get oil fouled from the inundation of oil which then generates a near dead short for the spark to follow from the coil - the high voltage arc will follow thru into ground outside to the cylinder head versus firing in the spark plug and cylinder.
