Weaping gear oil at your drain/fill plugs? Most common cause is a worn copper sealing ring. 22 x 27 MM
copper washer gaskets
If you have any weaping of fluids from your fill plugs this is the cure - easy to do while you are doinf a PM fluid check or change and you might as well buy the hex fill plugs so you dont have to screw around with the old pain in the butt allen factory fill plugs any more!!!!!!!
