I seen this posting and figured Id add what Ive found out about the issue. I have a Grand Am with the 2.4L Quad 4 in it that has the same issue with the oil vapor separator. I do not think you cant take it apart to clean it. Most likely you will not find it at a parts retailer, however I do know it is still available from GM Direct online or their dealerships. I believe it was around $45, I'm pretty sure the hoses don't come with it and it can be a pain to remove the old ones without damaging them. So if doing the replacement yourself take your time and be patient as I'm pretty sure the replacement ventilation hoses cost more than the separator itself. If you damage a hose it must be replaced with hose that is oil resistant, heater hose is not. If need be, places that repair and deal with heavy equipment sell oil resistant hose by the foot for a decent price but it obviously wont be preformed and may be troublesome to route.
If you do not wish to go through the trouble of replacing it, lack the ability or cant afford to pay a repair shop there is a simple method that will help prevent the oil from making it into the intake. Simply build yourself an "oil catch can" that can be put in line with the vent hose that attaches to the underside of the intake tube. The idea is to use a container in line to reduce the velocity of the vapor allowing it to settle. You will need to empty the container from time to time but it will help prevent your intake system from getting built up and/or fouling out plugs constantly. Just remember to small of a container wont slow the air velocity down enough to allow it to function. This will get you by till you can replace the vehicle if you plan to or get it fixed when you can afford to. If your not sure how to do this just Google "homemade/DIY automotive oil catch can" and you will find plenty of info on them.
