Ask your engineer where it is leaking from, the simple expediancy of putting his hand over the exhaust or airbox will tell you if it is valves, it hissing out of the dipstick hole tells you it is rings......... you may well find a good run and a squirt of oil will bring them back up..... if it is indeed rings this may simply be they have chattered round and the gaps have lined up, pulling the cylinder and repositioning the rings will cure that, also a leaking valve can be fixed by lapping the valves in or replacing if worn when the cylinder is off......... A top end overhaul is another option if it is valves, where the guides and valves are renewed......... incidently, Continentals do not like longish periods of unuse, the cylinder walls tend to corrugate for want of a better word. and I would recommend giving it a good run every month or so getting it nice and warm.
Either way ask your engineer as said above, a good engineer will be able to advise you and if he is not worried I wouldnt be, most of the Conti's I have dealt with over the years seemed to have a compression across the board into the mid to high 60's where as the Lyc's seemed all to manage the low to high 70's
