it may just be the fact that u got a new PCV valve and it was clogged before and now its flowing freely....cuz i have an oil catch can on my non boosted engine and it barly ever has to get emptied.....i think its just boosted engines that get all that shit but like i said it may be the fact that u got a new one and the other one was clogged bad or somthin....if thats not it then it sounds like rings....but dont jump to conclutions yet....thats all i can think of tho......
