Default 1982 Brat Oil in Aircleaner from breather?

Hey guy and gals, I am new to the club so I should say my name is Tom and I just purchased my 1982 Brat GL 3 weeks ago, running and in sort of decent shape for $900(not bad). Anyways, the car has the 31 year old blues right now with a myriad of rubber and plastic parts messed up, and general wear and tear items going out.

I'm working out most of those problems but, currently I'm rebuilding the carburetor(which is not in good shape) and got to wondering about the oil in the air cleaner. It's clearly motor oil and since there is a lot of oil in the passenger side valve cover breather hose and the inlet on the air cleaner I know it' coming from there. now I've read in some forums about other cars(Chevy big blocks mostly) that this can be cause by worn rings, vacuum problems, bad pcv valve, various other things. I'm curious to know what exactly can cause it in the brat and if I'm missing any parts that should be there.

I know the PCV valve in the engine is bad but, it's not connected to that hose in anyway. There is no filter or valve in that hose of any sort(should there be?). Other than that the engine does have quite a few vacuum leaks, missing vacuum and emissions hoses, is in bad need of a tune up, has bad ignition coil, etc...All of this seems to be causing missing, occasional backfire, and stalling. Could any of that be causing the oil to come through the breather? Anything else I should look at?

Thanks in advance for any answers!

-Tom

Sorry just rereading my post...to clarify a hair I meant the PCV valve isn't connected to that particular breather hose, it's connected to the breather on the driver side only.

If the HG's were bad there would be frothy/milky oil in the breather.
Blow-by is common with the EA81's, a little bit of oil in the air box wont hurt anything.
