While looking at the scheduled maintanence I saw that the PCV valve should have been replaced, but I have never done that. I've seen some different PCV valves out there. Any suggestions on which one to get? Does it even matter? Is it something I can do by myself?

 

yeah, it's super easy. Just get the one for your car, pop the old one out of the driver's side valve cover and swap it out. Takes longer to open the hood than it does to replace.
