Hi Anthony,
A pcv scheme is an acronym for positive crankcase ventilation and that scheme takes the blow-by vapors out of the crankcase and feeds them back into the intake manifold where they're blended with the air/fuel mixture and burned (again). It helps keep our air a bit cleaner and some think it may help your engine smell a little better when running...an early effort to reduce smog in bumper-to-bumper or slower city traffic. As Bartamos mentioned the tip-off was the grommet in the oil filler cap. Good that it ran for you. Now it is a matter of finding out what parts need attention and all of that. There are lots of folks here who can help. Please ask as many questions as you want.

Usually I'll start with the fuel system, follow that with the cooling system, make sure the oil is good and the oil level is right (and with no water in it), check the ignition system and timing and then start figuring out what's inside...solid lifters or hydraulic lifters, good oil pressure or weak oil pressure, that sort of approach. Later it will be good to do a compression check and also see what's happening with engine vacuum. If there is an O'Reilly's or Auto Zone near you, they'll loan the test equipment you'll need (for a healthy deposit which they'll give back when you return the stuff).
