In the Service Manuel, the diagnostic for the PCV valve is to squeeze the tube, and there should be a clicking sound.

well, i failed that test...there was no clicking sound.

then someone suggested that I take the pcv valve out and shake it and it should click around...well, i failed that test as well.

so i have a couple of questions.

1 - what causes a pcv valve to fail?

2 - does a non-functional pcv valve lead to increased oil consumption (I am losing 2 quarts of oil per 2,000 miles)

Thanks,

Jeff

a pcv valve will rattle when you shake it. pcv's usually fail as a result of oil blow by especially if that oil is old because it will gum up and cause the pcv to stick.
2 quarts / 2000 miles is kind of alot! i dont think thats the problem...

my pcv valve does not click when I shake it. it clicks when I tap it hard...like hit it.

should i replace my pcv valve?

yes...i consume a lot of oil and i don't know why. i am going to get krankvents and see if that helps.

i will do a leakdown test soon too...last time i did a leakdown, i had 6% leakage across...so i don't think its damaged rings...

since i will get krank vents eventually, should i just keep my pcv and gut it?

whats the harm of driving with a pcv that doesn't work...i suppose my engine can't create good vacuums...is that the extent of it?

krankvents
worked great for my oil consumption problem. hes having a sale on them now. i read it the other day.

keep your pvc valve. just add the krankvents to it.

but if my pcv valve isn't working right now, what good will the krankvents do?

should i gut the pcv valve? that would mean that the pcv valve can never fail if it's gutted right?

Dude, just replace the gummy PCV valve. They are like the world's cheapest auto part -- even at the dealer.
