You could always JB weld that. But, sometimes OEM is too expensive.

$52 here :

Engine Valve Cover Camshaft Rocker Cover For Chevrolet Cruze Sonic Aveo 55564395

And the picture confirms the PCV valve location. Make sure it is hooked up.. Might be "free"
I had a look at my service manual; and I found this passage describing how the PCV system works on the LXV/LDE/LLU/2H0 engines.

From what it describes in the Incorrect Operation table, it looks like the calibrated orifice in my valve cover is leaking. And I can kiss $165 goodbye; because NOBODY but GM has that valve cover!
