Steve,

The short answer to your question is you probably have worn piston rings and are getting a fair amount of blow-by of combustion gasses into the crankcase.  While annoying, consider this 'normal' for the age of the car.

As previously stated, do not pipe this vent directly to the back of your carb or else the oil will gunk-up the carbs and pretty much everything else.  The last customer of mine who did this had his piston rings literally fall to pieces.  The environmentally friendly thing to do is install a catch-can.

Check my older posts regarding my procedure for purging the crankcase.  You want to give your rings every chance to seal with nice clean oil free of any sludge. 

The only 'fix' is to machine the liners and install new rings & pistons.  If the car is running well otherwise, I wouldn't make that leap just yet.
