Find the oil pan gasket, and remove sediment. Keep a bucket below the pan, remove plug and drain all oil. Put back the plug, and fill up the pan. If you see oil pooling around the edges, then the leak is there in the gasket.


Check if there are any multiple leaks. If there is more than one leak, then the reason may be the crankcase pressure. Since there can be different causes of crankcase pressure, you should take your car to a mechanic or an auto repair shop to get the problem diagnosed and repaired.
