You might try searching for a PCV valve instead (Positive Crankcase Ventilation). PVC stands for Polyvinylchloride, your basic plumbing pipe.

It looks like the same basic valve Chevy has been using forever... Shouldn't be more than a few bucks and EVERY auto parts store probably has at least one in stock.

Isn't the pcv valve built into the valve covers on these engines ?
You experiencing high oil consumption ?

Here: https://www.youtube.com/watch?v=IwSdfkoSFiw Not a very good vid but he shows the underside of the valve cover and says the PCV valve is built in.

It isn't real a valve. More of an orifice.

If you are speaking of the orifice type, they do not require replacement. Usually they need cleaning only.

You can simply shoot carb cleaner down the tube for a while or run a can of kreen through the fuel and oil as directed.

This is a common problem on our high mileage trucks here (GM).
