200 tdi - bit of oil in the air filter

Ive a 1990 90 with a 200 tdi in her.

Just checked the air filter thismorning, and there was a tad of oily liquid in it?

Bad news?

Mark.

Would that depend on the last time you checked and how clean it was back then? Would knowing mileage help in guessing?

I remember threads about engines running away and self destructing on the hard shoulder once they are running on the engine oil, any mechanics out there able to tell me if this happens with other vehicles, and if for similar reasons.

All the best

Some oil in the air filter is normal, how much is normal is hard to quantify.

Should you engine run away, just stop, put the handbrake on, stick it in 5th with your foot on the brakes, take you foot off the clutch and it will stall. No problem, no damage (unless you've managed to use up all the oil - but you'd have to do some seriousl not looking in the mirrors to do that!).

Normal to an extent. However, there is a cyclone device bolted to the side of the rocker cover which will be of painted metal in your case and a larger plastic device on newer models. This has in fact got a service requirment and needs taking off and cleaning very occasionally. In all probability it has not had a clean in the last 15 years and is now overdue for a flushing. This will renew the effectiveness of the oil separation from the crankcase ventilation which is connected to the inlet manifold. Of course your engine could be excessively worn and a clean cyclone will be overwhelmed, but it sounds unlikely.
