It's usually caused by a lot of blow by in your engine worn ring's.How do you know you have high crank case pressure?Is the vent that goes into air cleaner from your valve cover clear?Is your pcv not all sludged up?

Are you burning any oil?If so how much in 2,000 mile's?There is no baffling in that valve cover so if there is nothing to stop oil from blowing out without the cap.Is the breather tube that goes from the valve cover to the air cleaner clear and not restricted?

Saturn allows 1 quart per 2,000 mile's so 1 quart in 3,000 mile's your doing good.
