I have a 2008 Saturn Outlook with a check engine light. Brought it to the dealer for diagnostic. Mechanic said the mass airflow sensor needed to be replaced and also said the PCV tube was fouled with some slimy oil-water mixture that was getting in the intake. Also said the PCV was part of the valve cover, and that the cover needed to be replaced. My usual mechanic was too busy to do the repair, but ordered the parts for me. He told me that they cahnge the design in 2009, and the cover didin't need to be replaced. I now have a new PCV valve, but can't figure out how to attach it.. Has anyone done this repair? Thanks
