I guess the question really is, should i change the K&N back to a paper filter before i take it in for warranty work?

Technically, it won't be a problem.

BTBH, I'd go back to stock to reduce the possibility of being blamed for the failure.

Since you asked,

Yep, very common.

Nope, it'll happen again. It's a flawed design and despite the revisions they've made to the design over the years, they still fail.

Might want to reconsider the 'It will fail again' thoughts.

The techs. at the dealer I hang out at (always trying to get juicy info for ya all) agree that the manifold being supplied for well over a year (might be over two years) uses a different and far more robust check valve retaining disc.
They indicate they have seen no failures (yet) of this newest version.

Since we all have come to the conclusion that the check valve failing is the most likely cause of the burst disc failure, I think the OP's failure/ repair will likely not recur.

This is still the engine found as an option on all Sonics, the only engine available in U.S. destined Trax, and the base engine on the Buick Encore, so it continues as a bread and butter engine and improvements will continue.

Same dealer says they just about never see water pump failures on 2015 and up versions of this engine as well.........one here or there, but nothing like the 2011 through 2014's were having.

Did these parts make it into the resupply chain by 2016?

My own 12 had both the manifold and valve cover changed with what they claimed were the "latest" revisions of said parts last year. VC #3. 20k after I sold it, I saw that it had the valve cover changed again.

The newest manifold should have been the only one available through 2016 if my sources were correct.
Doesn't mean the disc can't ever fail again but they lead me to believe that along with the manifold the cover failing is quite uncommon.

My 2012 LT has kicked out code P0171. Engine is running rough as well. I have noticed oil drops on the garage floor recently. Dealer said it's the camshaft (timing) cover. Is there a seal that needs to be replaced 'cause reading through this post it doesn't sound like it. Also, could a somewhat mechanically-inclined person (me do this job without much trouble?

Most likely the cam cover requires replacement.....the burst disc (non-serviceable) that is part of the cover has torn.

Upside: reasonably inexpensive.
Downside: Usually fails because a check valve, that is part of the intake has failed, exposing the burst disc to excessive vacuum.
This requires manifold replacement.
