Check the easy , obvious first,, OIL, FILTER, CLUTCH cover, etc.. Also the seal rings on the coolant pipe that goes into the pump are suspect for leaking and not showing any obvious clues ( loss of coolant). As for the cam chain, I would not touch anything there until you can truly access the oil / coolant. No point in diving into extra cost . Yet.
