You could do like some older cars have - run a vent line from the cap to the intake tubing behind the mass air sensor. Older cars returned the vapors to the air filter, but this might bugger up your mass air sensor.

That way, your engine could burn the oil.

You could also add an old fashioned pcv valve - they were a short, wide tube with a ball inside to act to regulate the flow of pressure. any auto store should have one.

I found several articles about pcv valves and catch cans on google, including a valve that is adjustable.
