Part 2 of 2 - Assembly - Replacing piston rings on a 1.4 Turbo (Chevy Cruze, Sonic, Encore)

Another Chevrolet Cruze in the shop today for the same deal - bad head gasket. After replacing the gasket, I found that it was low on compression. In last week's video, I showed you how I tested compression and discovered it was low, and how to disassemble the engine. Today, we're putting it back together.

Here's what I believe happened - this engine was allowed to run extremely hot - overheated, in fact, for an extended amount of time. Probably until it finally stalled out or the driver reached their destination. This allowed for glazing of the cylinder walls, leaving them shiny, as you see them in the video. Glazed cylinder walls causes low compression and increased oil consumption (although I did not notice any blue smoke from the tail pipe).

Once I completed this project, my compression came back up to within spec, and the engine is finally running perfectly again!

The Cruze that I'm working on today is a 2013 (I think I call it a 2012 in the video), but the procedure is identical for the 2010, 2011, 2012, and 2013. I believe the engine changed slightly for 2014 and newer. It is also the same engine that is used in the Chevy Spark and Buick Encore.
