Quick update....I've put 30k+ miles so far on the external PCV....only change i've made is that a catch can was added 9-10k? miles ago.
I see that someone posted above that the dayco hose collapsing. It's been averaging 90 degrees where I'm at and I've redlined 1-3rd gears without any issues. I've repeated this many times over the past month without any issue. I wonder if this is a 957 issues? as the person posted has a 08. My 2012/958.1 does not have this issue.
Sweet! Just ordered all the parts you mentioned, gonna do it over the weekend. Can you share an image how you installed the catch can and which one ?
Both of mine made different noises that could be traced to the back of the engine but it was tough to pinpoint. Covering the hole and having it go away was key to diagnosing. My 2009 was throwing codes, the 2016 I only heard so possibly caught it early.
I did the aftermarket PCV repair rkxtexh.com on my 2009. 2016 was covered by CPO so new valve cover. The external fix should stop the noise as that is basically a whistle or harmonic sound due to air pass through that shouldn't.

It was indeed the PCV, got a mechanic stethoscope, tested all pulleys they were fine. When covering the hole, the noise changes its tone. Weirldy enough I am not getting any codes. Oil pressure is fine, no misfires, air filter is clean. Found some oil residue on the PCV hose going into the engine.

Job was relatively easy to do, the "squeak" noise is now gone! The only thing that worries me is the "durability" or flexibility of the Dayco hose. I've driven the car a bit after doing the conversion and the Dayo hose looks difference (like vacuumed)
May this cause any issues or mess up the oxygen/oil mixture back to the engine? Attached pics

if i may ask, which metal pipe did you install and how?
I used a 1/2" aluminum tube that i had. I cut a small piece and a large piece to fill in the straight sections. I just used motor oil on the inside of hose and pretty much pressed the tube in. The 1/2 galvanized conduit mentioned by bartekgombos is pretty cheap from lowes or home depot. I think around $6 and seems like a good option to stiffen the hose. Just have to make sure it doesn't collapse at the bend
