The joys of Injectors being under modern day common rail engines rocker covers. I wont go into the Brand of vehicle but this is what is currently happening to a lot of 1KD-FTV engines. The injector seals leak allowing combustion carbons to sneak up past the injector and into the engine oil. The issue arises when the carbon bits (nice, small and hard) get washed down into the engine's sump and sucked up onto the oil feed pickup screen.
