The cam is lubricated properly from splash. There are no engines that submerge a camshaft intentionally. Too much windage causes heat build up and foaming. Race engines run dry sump systems and actually keep the pan near empty. Almost all engines have the dipsticks calibrated so that the full mark is actually an overfull condition. This is to accommodate normal losses and inattentive owners. Installing an oil temp and pressure gauge will show the harmful effects of overfilling these engines. Not only do oil temps rise, but watch the falling pressure as the oil gets aerated. You still need to find the leak though. Check the breather mounting to the engine block and the hose to the air inlet.

Curt: At the full mark the cam shaft is submerged in oil, the only source of lubrication for the lobe-to-tappet surfaces. The shaft is ABOVE (out of) the oil at the low mark.
