[QUOTE="AApple, post: 140725, member: 56"] The "ribbing" on any seal designates the seal as a [b]directional seal[/b]....meaning it is designed to seal a component that rotates in a specific direction ONLY. In this case, this seal is meant to seal something that rotates clockwise within the seal. If this seal was installed on something that rotated counterclockwise, it would leak profusely. A counterclockwise seal would have the ribs slanted the opposite direction. There are seals that are bi-directional, also, and the ribbing on those look kinda like a cross-hatch pattern. MOST seals that will work in either direction would be smooth on the sealing surface, but Honda does theirs this way, with the ribs. [GALLERY=media, 25733][/GALLERY] So...suppose the cam seals on the GL engines were directional. This would mean there would be two different seals for the front and rear(the seal pictured is a crank seal, which only rotates in one direction), because the same seal installed on the other end of the cam would have the cam turning in the opposite direction from the front. Chances are, the cam seals are NOT directional, so this shouldn't be an issue. I can't say for sure, but I do have some seals at home I could look at to verify. [/QUOTE]
