My truck would leak engine oil when parked on an incline. Figured it was from the oil cooler , but after a good look. There was no oil on the bell housing or back of the block that I could see. Cleaned everything up and parked on the flat ground for a week, no leak. Parked on the incline and sure enough, drips on the driveway the next day. Took it to the dealership as it is still under warranty. They called and said it needs upper and lower oil pan gaskets. Dropped it off this morning and will pick it up tomorrow. Hopefully that cures it.
