Holding Idle & smoke in oil filler neck

Two problems:

My 1973.5 911T won't maintain idle in neutral (e.g., while waiting at a traffic light). The engine cuts out so I have to keep the hand throttle engaged. Idle has always been a little touchy when the engine is cold but now it has trouble holding it even when at operating temperature.

When I check the oil level, after getting it to proper temperature, I find smoke in the oil filler neck, it is quite visible but not what I would describe as “thick.”  It also enters the air filter box through the breather hose, as does some engine oil.  

Is any of this terrifyingly abnormal in the CIS engine?
