You probably know if it's clogged up with oil and stuff it will not allow air to flow through it, at that point it's bad.
I read the manual and it doesn't mention much about the 5.7s PCV valve. The inlet hose is in the back of the engine... hard to get to. I guess it could be removed and then you can check the air flow through it.

The PCV should be good for several more K... probably 60+

Interesting 6-9K replacement, I'm big time over due at over 30K.
Do you have any idea Majin_Neon_00 if there is a valid test for the PCV valve or is a just replace it thing.
Pollution control valve is another definition for the acronym PCV, one of them tomato-tomato things depending on the school and time period of learning <= most of us are shade tree mechanics  . Just to keep the peace all of us can probably agree its a one way valve that allows blowby out with no backflow.

Most people use the rattle test, if it still rattles its good, but i really dont go by that, if there is oil on the bottom of the PCV valve then there is oil inside the pcv valve, so as a rule i change it ever two to three oil changes. Anyways it helps with your idle keeps it nice and smooth, or as smooth as it will get. It also effects gas millage so thats another reason i change it so often, and seeing as how they are normally cheap to replace there is no reason not to.
Which brings me to remind everyone that even though antifreeze says it will last 150,000 miles you should still replace it every 30k to 35k, and remember to check your hoses and that your Transmission fluid needs to be changed every 60k or the second time you replace your antifreeze you should replace your transfluid. and dont forget at 60k to change your rear diff fluid also (you charger owners.) Use Mobil 1 synthetic gear lube, makes cars happy.
I use only Mobil products with the exception of K&N air and Oil Filters.
And to the rumor of K&N air filters being no good, remember F1 cars use K&N filters, and everyone wishes they had A HEMI so keep it clean!

Thanks for the helpful information. How can you tell when the PCV valve is rattling? Is this something it does while the car is on?
No doubt about the anti-freeze/engine coolant change time. I have around 30k on mine and the antifreeze/coolant is a rusty color. According to the owner's manual its time to change it out.

I believe you would pull the valve off and give it the old shake test.
