Default Catch Can Paragon HTC Install

2023 HTC w/ Mag Ride
Received product, and I am in Calif. UPR would not ship to Calif. Paragon's quality is good. Paragon's price is attractive.
No paper instructions, but a phone scan icon to link to; otherwise, YouTube search.
The YouTube video I watched was installed on a coupe, and the car's oil/air lines differed from what I received.
Dare I say, some mechanical skill is needed for this install, mostly because of a lack of HTC precise instructions and the Paragon hose ends....with 1 being easy... I'll rate as 2-4.

1) If you modified your HTC with an Engine manifold painted Cover, it would make the job easier if you removed the cover before removing the OEM oil/ air lines.
Best advice: On an HTC remove your engine cover as step one.
2) Important... with mag ride on the shock tower, there is a hole in the top of the tower, and that hole is large enough to drop the catch can's bracket mounting bolt nut into the non-accessable area of the car....ask how I know LOL.
Best advice: Place a piece of tape over that hole !!!
3) The mag ride wiring... Paragon's video shows disconnecting the wire connector and the "fir" tree clip from the harness.... I did neither.
I seems to always struggle release GM wiring clips
I mounted the bracket, then pushed in the clip/ fir clip before mounting the can.
4) The hose ends differ from OEM, yet both OEM and Paragon's can be removed by pressing a gray clip, but Paragon's gray clips are difficult to release (small hands or an assistant could be an asset).
Also, the front hose on the valve cover is taller and lacking the bend angle that the OEM has, which made the following sentence necessary for me.
I found releasing a third hose, the one in center of the valve cover, and it is a larger diameter hose, as I described here since I do not know its exact name as I write this.
I found releasing and lifting that hose end up necessary for access and to install the Paragon hose end on the valve cover nipple.
Best advice: don't push the hose ends onto engine nipples until you are 100% certain of your routing.
5) If you modified your HTC with an Engine manifold painted Cover, it would make the job easier if you removed the cover before removing the OEM oil/ air lines.
Best advice: On an HTC remove your engine cover as step one.
6) The OEM hose retainer clips, along the passenger side engine valve cover, will secure the Paragon hoses, although the Paragon hoses are larger in diameter than OEM.
Best advice: use a small screwdriver to lift the clip over and against the Paragon hose to secure.
7) Routing, pay attention to the original route from the hose around the bracketry from the front valve cover nipple to the intake nipple.
Then Paragon hose routing could be in a few different ways.
Also note, the hose ends on the catch can itself, do not appear to be removable without scratching the assembly's paintwork.
FWIW: In my case, I added a piece of felt between the painted engine cover and the hose to prevent future scratches and also added 4 or so zip ties to bind the two hoses together as a unit.

In the "What did you do to your C8 today" thread I'll post photos soon.

In closing, I love the debate of catch can vs no catch can.
GM engineers vs. gearheads vs retailers.
The big question I suppose, "Does a catch can installation increase the amount of oil that now flows through the hoses?
I don't know.
One item no one seems to mention in the debate is the OEM system is Smog abatement related, uh, no other reason to route the gases to the intake?
Unless, the GM engineers want to lubricate something in the intake track?

I installed based on reports and videos of "x" number of ounces of oil (noting some with water - perhaps caused by the catch can, and some with fuel "aroma") on street-driven Vette during 5000 mile intervals.
Plus, modding is an addiction
