My '08 Owner's Manual says first inspection of the PCV valve is 60K miles, and every 30K miles thereafter. Other year Owner's Manuals have different intervals.

Inspection involves removing it, looking for damage/blockage, and shaking it to see if the "bullet" inside is free ans still spring loaded.

Cleaning it is not recommended.

Replace if it's plugged, or doesn't pass the "shake test".

But, if you pull it out for inspection, might as well put a new one in. They're pretty cheap.

 

go figure. the owners manual would actually have that in it. I really should read that thing. Thank you for the post. Mine is an 08.

Dude that is classic. Sounds like somethign i would do for sure.

 

Where is everyone getting their PCV valves? Dealership? Online? I've gone to all my local auto parts stores and nobody has them.

 

Napa has them (at least, mine did). I think it was $10.

 

Thanks bud! I haven't been there or the dealer. I will try napa in the next town over!

 

Just picked mine up. Part number is: 2-9555 from napa. Cost a whopping $10.84 with tax. Installing here in a little while.

 

Just finished. Zip tie trick didn't work. Mutilated the old valve and used vice grips and brute force to get that puppy out. The new valve popped right in and I could pull it out by hand. I snugged it in and put everything back together. Purrs like a kitty now and idles at a lower RPM.

 

I think the rubber gets hard after a while, causing the problems people are seeing trying to remove the valve. I recently had a difficult-to-remove pcv valve, but the zip tie still worked with a pair of extra pliers to hold it.

 

I'm just hoping the new valve stays put. It wasn't super loose but came right out by hand.

 

There is the possibility the NAPA valve is slightly smaller than the OEM valve.
I wonder if it has the same flow and spring pressure as the OEM valve.
I might get one and dissect it for comparison. I've recorded all the numbers for the OEM valve.
