Oil blowing back into air box (1979 245 B21 M46)

[waterman72]

Hoping for some help or direction here. I have oil blowing against the airflow, into the airbox and spraying the bottom half of the air filter with oil and eventually leaking out of the bottom of the air box.
1. I have checked and cleaned the flame trap.
2. I have checked and tested the Climate Control Valve and it is working properly.

Car seems to run fine (I've only had it for 2 months) gas mileage may be a little off. Any ideas what else it could be?

Thanks in advance, any help is greatly appreciated.

Well, see if old faithful is blowing...

Remove valve cover cap...start engine when warm...have someone increase RPM while the palm of your hand is lightly over "old faithful."

Is there pressure?
