I got the updated GM PCV part# 12572717 $6 or 7 bucks and GM vented cap ACD# fc219 GM# 12589430 $10 bucks and since then, during my last 2 oil changes i havent had to add any oil before my usual 3,000 mile change. usually i made it to about 2,000 miles before i had to add about a 1/2 to 3/4 of a quart , So luckily i have been about 6500 miles and i havent had to add a drop of oil to my car. And mine is a daily driver that is driven pretty hard. I don't use a catch can either though i once considered it until i had luck with the new PCV and Cap but i have heard mixed results with the Vented cap and the new Fixed orfice PCV for some people it has worked and some people it didnt i guess it's just the same as some people not burning any oil at all but for under $20 bucks i figured it wouldnt help it sure was alot cheaper than buying a catch can
What oil are you running??? have you tried a little heavier grade??
