Oil Leak from top rear side of engine

[Tom Forletta]

Hi All,
I’ve got a small slow oil leak originating from somewhere near the top rear end of the engine on my 2005 ST1300. I was thinking it might be the gallery plug or possibly something else. The oil seems to collect around the gear shift shaft but I can see that it’s coming down from above the output shaft.
Any thoughts would be appreciated.
Thanks

Might be a leaky valve cover gasket, specifically the circular part the seals the spark plug tunnel. If oil leaks from there into the tunnel on a rear cylinder, there’s a drain passageway out the rear of the cylinder head.

Thank you, I’ll check that out.

Also, possibility coming from the starter. But changing that out will be a BIG PIA!
