2005 PCV replacement

Hey how often should I replace the PCV valve on these cars? Is there any way to tell if they need to be changed? It is on the passenger side valve cover, correct? Thanks guys

Re: 2005 PCV replacement

If the valve is loose and rattles when it is shaken, it is most likely OK. The real test is a vacuum test. It should close when vacuum is applied. Later model PCV's will cause a CEL if they stick. I have personally never had a PCV valve fail, but have seen them fail in cars with excessive blow-by.
