Does my motor not have a PCV Valve ??

Does my motor not have a PCV Valve ??

Postby yzf125 [OP] » Apr 07 2020, 5:41pm

Hey guys, I don't see a PCV valve on my 2012 GMC Sierra Vortec 4.3 ?? All I see is a vent to the manifold on drivers side and a vent to the air intake on passenger. So this model doesn't have one ?

I believe a lot of the newer engines do not have one any more. They are built in to the engine itself, not really serviceable like they used to be..

It's a fixed orifice system now.

I found this OP. Looks like the valve is part of what would be the hose for the valve possibly. This part may not be the exact one needed for your truck and is an example. It would seem to be serviceable to answer that question. Not sure how this meters since it looks like a simple tube.

Edit:
I found this pic. Not sure if it helps or not. I'm not sure if this is before or after GM updated the PCV and they started being installed.
