crankcase venting and oil burning was [Vwdiesel] turbo 1.6 or non turbo advice

[Bart Wineland]

Well I went out and checked as soon as I read this to be sure. My engine is 
from '86 but has a  older vacuum pump. It does vent back to the crankcase. 
 From the top of the pump is the vacuum line to the brake boost, a small 
yellow plastic line that heads for the dash for climate controls and has a 
third small hose that is hanging free.  I thought the third hose was 
plugged off but when I look at the "plug" it actually has a very small hole 
in the center? After looking at the set up I have to admit I don't 
understand how it all works. Wouldn't the output of the vacuum pump 
pressurize the crankcase? How could that ever be good? Are you saying I 
could pull this line off the bottom of the vacuum pump and just tie it up 
to vent the crankcase to see if it helps my oil eating?

Thanks,

Bart
