I have a 2011 Chevy Equinox with a bad oxygen sensor, it’s burning oil rapidly weekly and and yesterday while going up a hill ALOT of white smoke was coming out of exhaust pipe. What’s going on with my car? ---

That’s an indication of a blown head gasket. [![](https://global.discourse-cdn.com/cartalk/original/3X/5/c/5cdd3604094e1d5d437f0305b719e38abf6b9300.jpeg "Civic Blown Head Gasket") ](https://www.youtube.com/watch?v=64YqIfGex1c) Tester ---

The piston rings are stuck, this causes oil consumption and smoke. There are updated pistons available for the 4 cylinder engines, the warranty extension for this repair has expired.
