Hi, Once every 3-4 weeks the motor or trans burps oil on the back of the engine and exhaust pipe. It only last abour 30 seconds or so and stops smoking. If I carwl under the jeep when I get back the bell housing and trans pan show oil drops. The filter housing area is dry and I replaced the valve cover gasket. Any suggestions would be greatly appreciated.
