I got the Jubilee split this afternoon and got the clutch, flywheel and cam gear removed. Sure enough the oil gallery plug is in fact installed. It is a slotted flathead screw plug at 11:00 and it is behind the cam gear. The gallery plug on the front of the cam, is at about 1:00 viewing it from the front of the engine so they are aligned with each other. There was some oil mixed with water behind the cam gear cover. At the bottom of the cover area, there is what looks like a drain hole to go back into the crank. There isn't any water showing up on the dipstick, so I think the water contamination came in via the pump access which I don't have covered. I'll post a picture when I get home on Sunday. I've got the engine loaded on the trailer and I'll get it back on the engine stand so I can work on it. This does mean that the bearings are very suspect.
