O2 sensor does not even work when cold,
The system is in closed loop cycle, check if you have any stored stomp codes.

leaking valve cover gaskets? Letting oil pool around spark plugs...
Are you smelling oil burning as well?

NOT the gasket, how do u check for stored codes?
Thought it was the gasket, chaged it 4 months ago and saw no change, and ever since I bought the car it has this problem. Can it be sensor or what can it be, even when temp. is hot idling is bad sometimes and sometimes its OK, HOW DO YOU CHECK FOR STORED CODES IN MY 92 525I, M50 ENGINE?

Try replacing your coolant temp. sensor, it may be defective.

Check the condition of the oil fill cap, make sure it has a good seal when cold. New one is around $5+.
