hey for anyone that replaced a pcv valve, i bought a generic one at autozone and was wondering is it suppose to make a jiggle sound like somethign is loose inside when you shake it??? my oem one that i took off doesnt so i was wondering if the new one should

 

Yes it's supposed to jiggle. When it doesn't that means its clogged.

 

cool thanks

 

How much difference can i expect to see on mine with 109k, i am about to replace it...

 

Difference in what? Power? None really. Better gas mileage maybe.

 

It's more of a regular maintenance item, like changing the oil, except much longer periods between changes. There isn't really a difference, it's just healthy for the engine to do it.
