if you dont have Toyota's ..ahem... "Special Service Tool" you can tactfully punch a hole in the front of the seal (the metal part) with a scrtch-awl/icepick. Then carefully run a drywall screw into the hole and turn it far enuf to lock in. Then just grab the head of the screw with pliers and tug it out. Also oil pump drive cover O-rings can cause the leak. Most common is the seal.
