So ummm... I can't remember, and the WIS doesn't show. The water pipe that's located on the back of the head that runs to the turbo. Is connected at both ends with a banjo-bolt. Can anyone tell me if the seal-washer is on only the mating side (banjo-bolt -> banjo-pipe -> seal -Turbo/Block) or both sides (banjo-bolt -> seal -> banjo-pipe -> seal -Turbo/Block). I pulled them all off and ordered new ones and in the time to get them delivered I've forgotten.
