OMC Oil Loss/capacity

[sarmarracajm]

I just purchased a 1970 SS19.5 Slickcraft with a 1968 210 HP OMC inboard engine. I was shown clean oil at the full line at time of purchase.I ran it for two hours, no smoke, but noiticed vlave noise. I checked the oil, and it did not register on the dipstick. I added 7.5 quarts, which seems an awful lot of oil. It still is not up to the dipsitck. There is no oil leaking out of the engine or on the water around the boat. Any suggestions?

It's not in the bilge, is it? I wouldn't think more than 4-5 quarts would be necessary. Is it possible the dipstick line is plugged?
