HI the only way to find out is to pull the R/Covers off and take a look, if nothing is wet in the rocker shaft ends then check the oil return tubes from the camboxes, poss the cam seal/gasket leak, which end of the cambox is leaking,?? if they are ok the its the engine strip time to clean up/reseal and refit to car.
