1997 323i BMW "suddenly" has oil leak (driver's side/front) about the size of a dessert plate. Didn't have anything on driveway in the morning, puddle showed up in the afternoon. Oil gauge showed low and we refilled, but what could cause the sudden leak? Otherwise runs fine and no other problems.
Only way to know is to get under the car. Could be the oil filter housing gasket is leaking.
