Where is the PCV valve on a 1986 carbureted 1.9 engine and is it normal for air to be blowing out of the oil fill hole in the crankcase cover?

The pcv valve is probably on the valve cover.If the engine is blowing oil out of the crankcase or the oil filler tube,it could be the pcv valve.It could also be an indication of internal wear,such as stucking valves,causing the engine to build up excessive pressure.
