Q: Where is the PCV Valve located? on 2007 Chevrolet Silverado 1500

I have a 2007 Silverado Classic V6. We can't find any information about the PCV valve. My husband has decided that it doesn't have one. Now the Check Engine light is on and we're going to replace the Oxygen Sensors, but I thought I would check to see if there is a PCV valve and where is it hidden at?

The PCV valve on the V6 engine in your 2007 Chevrolet Silverado should be located in the left (drivers) side valve cover - a hose will be attached which runs to the intake manifold. Do you know the fault code that is triggering the check engine light to come on? If you can tell me the code I can be of more help.
Mr Taddei,
I am in ownershipof the same type of vehicle, a 2007 chevy 1500 classic w/ same engine. I've changed my fair share of PCV valves on multiple vehicles including the last 4 chevy trucks I've owned. But this one is throwing me too. I have looked for the standard line to follow (rubber flexible) to the valve, andd at the rear of the laft valve cover there is simply a nipple about 1 inch tall that is part of the valve cover itself. Looks to be a return line of some type. In regards to both valve covers this is the only thing between the two of them. Sooooooo ??????
I stand corrected! Perhaps I misread the question and was looking up information for a V8 engine. The 4.3L V6 engine used in the 1500 classic does not have a PCV valve. There is metered orifice in the valve cover that controls the flow of the crankcase gases.
