What is the most likely cause of an oil leak from the front of my engine. on 2002 BMW 325xi

I have already replaced the valve cover gasket. That seemed to help. However, the engine will sometimes run a little rough when I start it and the oil light comes on. If I shut the engine off after a minute and restart it. It will pure like a kitten and the oil light goes off. Could this have anything to do with the VANOS control unit? How do we find the leak? Thanks, Bill Poirier

Usually leak on front of motor coming from crankshaft seal.
Wow! A crankshaft seal leak on this car is expensive to fix, right? I was hoping it might have been the VANOS solenoid valve or the VANOS Control unit. They seemed to be a little easier to get at according to the repair manual. I will let you know what I find out. In the mean time I have been driving the car. It seems to drive and handle great. Thanks for the advice! Bill P.
