I just looked. There is a vacuum port on the throttle body on the front right side of the engine. If oil is being sucked throught that hose it will go immediatly into the front driver side cylinder (UK Right side drive). I beleive that is the Crank Case Ventilation. If there is an oiling issue, such as the case filling with oil, it will pump out of the case through that port into your intake manifold. If you pull the air tube off the front of the throttle body you can open the butterfly valve and look into the manifold. If it is wet with oil you have your route of travel for the oil into the cylinder.

If the parts of your oil filter clogged the filter, the case could very well fill with oil; unfortunatly, it would be dirty oil. Have you noticed any strange readings on your oil dipstick?
