Yes, it does have a pcv and the intake has to come off to get to it( at least if you treasure your sanity). The start of all the oil problems is usually the vacuum port ( two of them) gets stopped up and this causes the pcv to stop functioning. If you don't want to keep buying mass airflow sensors, you'll need to take the oil separator,supercharger,intercooler,and all related hoses off and clean them out. If you don't, all the oil will work its way back up to the MAF. The oil separator is pretty cheap, you can just replace it. The intercooler willprobably need to go to a radiator shop to get all the oil out. Everything else can just be cleaned out with carb cleaner. By the way, the pcv hoses will be hard as a rock(top two),so it's easier to cut them and replace them with the new pcv.Just be sure to clean the vacuum ports out with a wire or something. Hope this helps.
