Hello.

I am trying to locate the PCV valve on my Chevy Cruze. It is the 1.4L turbo engine. Could someone help me locate this? Thanks.

Did you ever find the Cruze PCV valve? I "think" is in the flex tube that runs from the center of the intake manifold casting to the input casting of the turbo. It doesn't seem to be replacable by itself, and may require the replacement of the entire tube.

It looks like according to GMPArtsDirect, the Valve and the hose are one unit and costs $50. But they do not describe where it is.

According to my 2011 Helms manual the crankcase ventilation pipe runs between the turbo and the camshaft cover. The PCV orifice itself is an integrel part of the camshaft cover.

I cant seem to find the hose from turbo to camshaft cover. This is for the 1.4T right.

Here you are. Open hood, look to the left most part of the top of the engine. You'll see a ribbed tube that has tape on it that secures a smaller tube. That is the PCV pipe and the charge air bypass pipe (which goes to the BPV/BOV)

Somehow I thought it was integrated into the valve (cam) cover. Somebody posted a thread about a pressurized valve cover that was leaking oil and the warranty fix was a new valve cover, not a separate PCV valve.

That might have been me as I had a hairline crack in my cam cover which caused an oil leak. They replaced the cover only which sloved the problem. The PCV valve (tube) is as as shown in titan2782's diagram and was not replaced.

Confirmed last night that there is a check valve in the PCV tube. It's located on the end of the tube that connects to the turbo inlet. I can blow from the valve cover side out but not from the turbo side out.

Not sure if there is still another valve in the valve cover at this point.

There is nothing in the valve cover.
Didn't think so, but I've never had it off so I can't say for certain. But, the service manual doesn't say anything about a valve in the cover (or the PCV tube for that matter)

The pcv valve is part of the valve cover. I had this replaced under warranty when it failed. Cost of the valve cover on gmpartsdirect is about $40.

Thread here: http://www.cruzetalk.com/forum/25-service-issues/9236-check-engine-light-32-000-miles.html
That's going to be the "breather valve" which is a vent either to the the intake or into the evap system. Breathers do not have check balls in them. Why would the PCV have two check valves? It's going to be for a different system or it's just a vent.

I'm trying to find info in the service manual, but it doesn't mention anything aboout the valve cover or a breather. It doesn't mention a PCV valve directly either so I have to see what I can find.

I think you are mixing terminology. The "breather" is actually just the tube that connects to the pcv valve.

In the case of the Cruze, the breather tube and pcv valve are all part of the valve cover, which is how it was designed, and it is unserviceable according to Chevy.

Negative.

The red line follows the PCV tube and as the diagram and instructions show, it's removable. The check valve preventing air from going back into the engine is located on the end in which I circled. If you don't believe me, please remove your tube and blow into both ends.

I'm not disagreeing that there is some type of vent inside of the cover which is non serviceable, but it isn't the PCV.

PCV and the tube is in fact "serviceable" because I just replaced mine with a new one from GM ($89). By serviceable, I mean replaceable :) When you purchase this part, it's called the "Charge air bypass pipe" and comes with the PCV tube (with PCV valve) and the actual charge air bypass tube which goes to the BPV/BOV.

Well ... if that is the case, then the service adviser misinformed me.
I haven't met a single service advisor who knew wtf they were talking about when it comes to the Cruze. Maybe in a few years? That's why we're here, to figure out all this stuff ourselves. I would like to know if anyone has a picture of the valve cover off so we can see what's under it.

As for "serviceable", I take that to mean it is not repairable.
Yes. The only way to repair is to replace :(

LOL! Alright, well, we are both right. I just got a call from the dealer, they said my PCV valve is stuck open and the valve cover has to be replaced. So there is in fact, TWO check valves in the PCV system, one at the end of the PCV tube and the other is inside of the valve cover.
