Its job is to keep the oil that sloshes around in the crankcase and oil pan from escaping out the back of the engine. Symptoms of failure are usually a wet area on the rear of the oil pan, an oily wet spot on your driveway or a completely oil covered transmission. Replacing this seal will ensure a leak free engine.
