Pcv valve issues

[klb]

I bought a certified new owned 2015 Chevy equinox. At 89,000 the pcv valve blew and I needed a new motor. It was under warranty but they fought me and tried to say I didn't change my oil. Which was not true! I always maintain my vehicles. Now it's at 150,000 and I have to ride around with a quart of oil in my truck to put in at least weekly. There is no leak anywhere visible but the oil consumption is ridiculous. Worst car I ever bought and they will do nothing.
