I usually do most of the maintenance on my car but things are little hectic and I didn't really feel like spending 3-4 hours replacing spark plugs so I took it to the dealer. While they were in there I went ahead and told them to replace the PCV valve. Apparently the PCV valve part number that came up (68083202AC) for the car didn't match what was in there. The new part had 2 screw holes vs 3 screw holes in the original. They said the hose fitting seemed different as well. The dealer did not feel comfortable using the new part. I asked them well surely this isn't the first time you have run into this...he said it was and hasn't had a chance to look into it so the PCV value didn't get replaced. Has anyone run into this issue? Assuming you went ahead and use the new part number with only 2 screws?
