Eh, a lot of old cars get oil up the pcv hose. Hell, a lot of cars in general. There's a reason manufacturers stopped putting the pcv breather hose near the air filter - it just gets the filter all soggy (and leaves oil deposits on the throttle plate) - so most modern cars usually have the hose routed to the intake or some place down the line from the air filter. I think your car should probably have a little square of felt in the air cleaner, over the pcv hose place. To sop up the oil it squirts out. Not 100% sure though.
