Re: Help! My air intake suck in oil!
if anything, the engine should be OK.. but the mass air flow sensor might be done for!
dunno what model is your ride... typically they are either hot wire or thin film type... the presence of oil can mess up the accuracy of the sensor as such the air intake will be inconsistent. Do you notice your rpm hesitation across the range?

i think what zag means in simple terms is do u have irratic engine idling, where the engine ki siao a bit (rpm needle jumping around) or even die off. just describe to us whether your ride feel any different after this oiling incident. if u are still not comfortable, can always pop by a workshop (preferably with bmw diagnostic tools) to test out your ride. spend some money for a peace of mind

Re: Help! My air intake suck in oil!
I'm driving the E39, so far no irractic engine idling and no rpm needle jumping around. However, engine seems to be slightly noisier and I can feel that the car is not as responsive as before (like a bit of lag) when I step on the accelerator. So is it due to the air flow sensor ki xiao liao?

Only got it service in Feb 07. Maybe I will just pop by a workshop that has BMW diagnostic tool for a diagnos, especially the MAF and see any problem. Thank you all for the good advice!

Re: Help! My air intake suck in oil!
that sounds like hesitation to me (not so responsive)...
are you still keeping the K&N filter or you reverted to the OEM paper type now? might want to do that till you are sure the oil is not messing up the sensor.

Re: Help! My air intake suck in oil!
Still using the K&N, thought the oil should be in the normal zone by now. If there are anymore additional oil from the filter, should have already gotten suck in and too late to do anything ...... Well, if you recommending to change to the OEM filter to see the sensor is ok, I think too late liao.

Re: Help! My air intake suck in oil!
In any case it should be fine.
You oil too much, put in the filter, overnight the excess just dripped onto the base of the airbox. If you MAF is farked, it shld idle poorly and drive poorly as well.
Your crankcase has a recirculating pipe back into the throttlebody. The fumes serves to lubricate your intake valves. All stock cars have this. So even if the filter oil gets into the engine, its ok.
