Quick while i have the truck in pieces at this moment

so im changing my sparkplugs on the 4.0 this very moment and since i had all the shit off to expose the drivers side is that a pcv valve on the valve cover in the corner ?? has anyone changed it ? should i change it ?

 

Couldn't hurt to change it if you have the part but I'm at 80k miles on mine and haven't touched it.

 

yeah im at 165k lol

 

Clean the junk out of the lines if you wish. But if it ain't broke don't fix it.

 

Will it make a Difference in anything if i do change it is what im asking

 

Not unless there was something wrong with it to begin with. FWIW, the PCV valve is sold as part of one of the dealerships 'tune-up kits'. I don't think it's overly expensive but they can wear out over time and let oil past.

 

ohh ok so one of them if its not broken dont mess with it lol
