Where does the Timing Cover Oil Seal go on 603 motor? # 0129975648
 

I'm working on a 603.961 motor and am gathering parts for a timing chain & guides job.

I see advertised for sale on pelican parts:
Part # 0129975648 Timing Cover Oil Seal

Does anyone know exactly where that seal is on the cover? I can't seem to find a spot for it.

The only seal I found to actually attach to the timing cover is via the oil dip stick, which is # 0179971648.

Hope someone can shed some light.

Cheers.
