This is from my mom's 2007 Equinox, LT V6 AWD. After taking over the oil changes a year ago, I noticed it using oil this week. Quite a bit. We dug into it today and found that the last time it was in under warranty for chronic air/evap OBDII codes, the dealership just cut out the PCV valve and used GOOP to install a straight-through piece of plastic tubing. No kidding.
This is what was installed in lieu of a PCV valve. The picture is on a mechanic's mirror as it's on the back bank and you can't visualize it directly:
My dad ripped out the tubing before I got a picture of it as installed (he's impatient). Here's a picture of the casting on the rocker cover; it may not be clear but there's a lot of crystallized sealant in the tube. Also, the replacement PCV valve we bought is way too big to fit, and there's no grommet in the casting to accommodate anything.
The opening is 5/8", and none of the parts catalogs or images I can find show a 2007 V6 Equinox looking like this or a PCV valve small enough to fit this. We have had this car since new so it's not like it's been hacked or by anyone other than the Chevy dealership.
I could fit a grommet and other maker/model PCV valve to it, but am baffled why this is rocker/valve cover is different apparently than any other shown for the year/make/model. Maybe that's why the dealership said "stuff it" and just "pulled a Clinton" and lied about fixing it a few years ago when it was last in?
