This morning I drained oil so that I could add the AP-205 Sealer. I drained a 1-1/2 quarts and the dip stick registered full. I started the engine and then re-checked and the dip stick said down 1/2 quart. I added back 1/2 quart and dipstick now says full. I'm thinking the previous owner had put an extra quart of oil in and excess oil was being pushed out thru the rear seal. I did not add the AP-205 until I drive around a bit to see if the drip problem has been rectified.
