Well, I would hardly say that it is worn out. I am not familiar with the details of your particular year of engine, but BMW builds one of the best Straight-six engines around. It could be as simple as a check valve, but based on your mileage, I would suspect the valve guides. Shouldn't be a job that would break the bank, but try to have this diagnosed before jumping in. If it is however the oil control rings, I do know on some models you can actually pull the pistons out through the bottom of the pan thus saving the cost of a complete rebuild (and engine pull). Find a good mechanic that knows the car and see what he suggests. Regardless, you still have a much nicer car than many of the new vehicles being sold today.
