Cruze 2013 1.6L Turbo PCV Valve

The check engine light came on my Cruze 2013 1.6L Turbo and when I checked the error codes it was P0171 (System Too Lean (Bank 1) , I suspected PCV valve. I got the car serviced at the dealer and asked them to check it out and they also came back and said its the stuck open PCV valve.

I know the **** valve is molded onto the cam cover and a genuine valve cover is $800 AUD :eek:. I have seen aftermarket valve covers for this model online for around $100.

My question is has anyone replaced theirs with aftermarket one and do they fit well & long lasing ?

or do I have to bite the bullet and spend $800 on a genuine one ?

cheers 😀

Welcome aahhh Back!(y) Where have you been for seven years?

And to add to what JLL said, the PCV valve on the 1.4 is in the intake and at the turbo. (two of them) The PCV regulator is in the valve/camshaft cover.

1.6L engine is slightly different to 1.4L in the video , but i guess PCV system must be the same . will have a closer look to see if I can identify the check valves

Does the 1.6 have the integrated PCV inside the intake as well ??

yes the PVC is inside the rocker cover , I've seen a video where it can be separated from the rocker cover body . if thats the case then I can replace just the PCV regulator .

This is much more than a place to just ask questions. We also accept answers! So when you start to figure out what to do, we would really appreciate anything you can describe as differences or maybe a completely different issue / fix. as we have little information on the 1.6.

yes i will be posting what ever i find and fixes here so that others with 1.6 can benefit from them. :)

I bought a after market valve cover from e-bay for $50. It arrived today, Will fit it in soon and see how it goes. Much cheaper than $700 from the dealer ! but dont know how long its going to last! I guess only one way to find out :)

I replaced the valve cover today. It was pretty straight forward. the old gasket was so stiff and like plastic. it snapped when squeezed, spark plug wells were full of oil as oil was leaking into them for a while now. cleaned it all up and put the new cover which fitted in nicely then torqued the bolts to the spec .

So it is the vacuum regulator in the valve cover. Does the rest of the PCV system look to be the same as the 1.6? If so you may be able to use a fixkit to help ward off a future failure as on the 1.4 the valve cover failure is just one of the symptoms of a PCV failure.

yes its the valve (diaphragm) inside the valve cover. the 1.6L PCV system appear to be different from 1.4. I dont think it has the check valve in the intake manifold like the 1.4.

Aside from getting a bit seasick in the beginning, I thought that was a pretty decent video. I would add that you may want to suggest torqueing the valve cover to 37 in-lbs first and then to 74 or whatever is required. I forgot.

haha....tanks! it was not easy to hold the camera with one had and do the job with the other hand. I could not find my head cam either....... I needed a dedicated camera person! :) Yes I did 2 stage torqueing but probably forgot to mention that in the video. Also after couple of days of driving it needed retorqueing due to the gasket settling in and flattening out and also the plastic cover releases some molding stress due to temperature cycling .

my fuel consumption has improved. Before PCV valve/valve cover replacement it was consuming 11 liters /100km and now 9 liters /100km ! about 20% reduction ! . Also I replaced the air filter.....well overdue ! :rolleyes:
