Warranty repair question

[daemontrym]

A few days ago i took my 2012 sonic in to get the pvc in the valve cover replaced.
When i looked on the repair form they installed a new intake manifold and valve cover.
It said the intake manifold was missing the non return valve per pip5197b. Has anyone heard of that before? The car ran great before the pvc problem, but runs much smoother now. I am wondering if the changed the design and it came with some pcm updates.

Makes perfect sense now, this is the first car i have owned with a turbo. I am only familiar on how na engine pvc systems work. All i know is that it made a noticable difference in driveability even before the cam cover stuff and fuel trim codes.

I don't know if this related or not but my car had the valve cover replaced before and just recently I noticed I'm getting a lot of blow by when the car is running and I open my oil cap. If left open for more than 30 seconds the car will start to idle rough and shake.

Had all this done on my 13 turbo, except intake manifold. Supposedly they just repaired the non- return valve. It was a new service bulletin in February.
I am having additional issues (just in the last few days) since the month long ordeal of my car being in the shop. It's been 3 months... Maybe I'll have to tell them to look deeper this time.

I'm on my 5th valve cover....

When the PCV goes bad, are there any external signs, or just blowby?

For me the car has always idled horrible, loss of boost and power. Stalled very easily (had to rev it high before changing gears). The last time was the only time I noticed oil leaking around the valve.

If you pull the coil cover off you'll hear the vac leak.

If your losing oil it's from the crank case being pressurized so that means the return valve is bad in the intake manifold. Make sure when your getting a new VC your getting the updated one. I think your on #5 because the dealer is giving you the old one

Ya, who knows. As long as it works most of the time...
