Has anyone else found oil in the bottom of the airflow sensor? If so, how does it get there? I have a standard air filter so that cannot be the source. It does not look to be coming down the hose from the turbo or the purge pipe from the charcoal cannister. The oil looks like fairly clean engine oil. I don't think the oil is causing any problems.

If it hasn't come from the filter, It may have come from the crankcase ventilation system. I don't know where it enters the inlet tract on a Scooby though.

Cheers,

Alex
