I may want to install an oil vapor catch can on my wife's Trax. How do I get to it? Where is it at?

The catch can takes in the oil vapor from the hose that comes from the engine to the PCV valve and delivers the oil-free air into the PCV valve and back to the air intake.

You then empty the can every so often (usually at oil change time). This then prevents oil vapor/sludge/carbon build up on the backs of the intake valves.

Decent catch cans go for around $30 USD but can cost much, much more.

Well, I answered my own question with a little Google and Cruze Forum help. No catch can is needed on the 1.4 GM engine as an oil separator is in the valve cover.
Do a search on the Cruze Forum which has a nice video and explanation of the system and any fixes that you might need.

It is strange You got a 2016 Trax with the B14XFT engine, I thought they were only A/B14NET engined till 2017.
Your engine should be like this one, LE2 engine option:

A nice, small and powerful turbo inline4 with GDI.

My 2016 Encore and 2016 Trax both have the same engine with RPO code LUV not LE2. So I assume this means fuel is injected in the intake and not the head.

Yes, it is a conventional system, still qualified as conventional by now.
There are two similar turbo engines - A14NET and B14NET, both "injected" into inlet manifold.
There is a B14XFT turbo engine that is direct injection(GDI), it is more torque-y and has more hps.

I suppose, judging by the hoses, that both can be fitted with an oil vapor catch can.

No catch can is needed on the 1.4 GM engine as an oil separator is in the valve cover.

A link would be nice))) Tank yoy.
