Finding a leak at the oil stand gasket on BMW's is been fairly common on six cylinder cars as they get up in miles. The oil will leak down the drivers side front of the engine and usually along the seam where the oil pan joins the block. Sometimes this is mistaken for a leaking oil pan, which is a much less common problem. So its important to locate the true source of any oil leaks to prevent unnecessary repairs. While the labor time and procedure varies some on the various models, it is basically the same repair. The photos below show the repair on a BMW X5 3.0 vehicle. Depending on the model, the intake often has to be removed.
