The description says it's for the 1.4L valve cover: Ventildeckel Reparatursatz Membran für Chevrolet Cruze Trax 25198874 55573746 | eBay
But I'm skeptical too.
I'll give it a try, can't make things worse.
That's a good pcv membrane. You will need to either heat up the engine or just get a hot air blower to heat the membrane cover and pry it carefully with a big fat flat screwdriver. The membrane cover can be glued back but it's only a one time job and you will only be able to glue it from the outside, also you will need to press that baby with whatever you find. I've put a dumbbell on it as it was a must to fix before the valve cover arrived and i had to leave town for more than 10 days. I still have the old one as a backup for the future emergency.
LE: buy it from alliexpress they arrive in about the same time. This are my ordered ones

Depends, 3$ vs 90 afm shitty ones, oem one is higher in the 200$
Where are you located that you're seeing those prices? OEM valve covers here are $65-$80 USD.

I may try to develop a process that allows one to remove those valve cover diaphragms and replace them cleanly. It would sure help the community if I can figure it out. I'd keep those diaphragms in stock as well.

Germany: I got a quote from my garage, OEM valve cover without installation 420€ which is the SRP from Opel.
Also found it for 200€ online.

That would be really helpful.
I ordered the membrane with cap included I mentioned above and will try it as soon as it arrives.
Let me know if you have any ideas especially which glue to use.

Can you find GM ones in USA/CANADA? Not AFM like doorman, GM made. I doubt there will be a fixeable valve cover. I would rather replace it every 7-8 years because it's plastic anyway and it will warp no matter what.

Hi can the orange check valve nipple in the intake manifold look like the picture but still cause issues? (Eg not seated properly or half of the valve missing and is there any way to check without removing intake) It is oily in there.Have rough idle, lack of power and blue smoke from exhaust. Corrugated hose can blow through and when sucked back it’s like you can feel a valve close but oily taste in mouth. Regulator diaphragm isn’t drawing any air. Do you think there are any other problems to check that would give similar symptoms?
Yes

My kit arrived a few days ago, way earlier than expected, thanks @XtremeRevolution !
I installed it today and changed the valve cover to a new Dorman.
Actually I wanted to try to change the membrane only, but as the membrane hasn't arrived yet, I decided to use the new cover and try to fix the membrane of the old cover later and keep it as a backup.

For the kit, I needed two attempts to place the clip inside the manifold, so it ended up a little bit messy in there.

I did some testing today, when the engine is not completely hot (even 5 minutes after turning it off), idle is very stuttering, even the gear knob started shaking and engine stopped at a traffic light. Besides that, everything seems fine, no fault codes, no smoke anymore, full performance.
And idle is fine when the engine is hot, so it feels completely different to the idle problems I had before.

What to do next?
I know Andrei had bad experiences with non OEM valve covers, but I doubt that it could be that bad?
Are there any other possible reasons for this behavior?

Vacuum leak or defective evap purge valve. Did you lose the retaining clip inside the pcv pipe manifold terminal?

No, I didn't lose it. Didn't find the hole, pushed too hard and clip was bent but I got it back out.

How could I test for vacuum leak or defective evap purge valve?
OBD plug is available.

Btw. I tested and cleaned the check valve at turbo inlet.
I think the whole sound changed a bit, but I might be wrong.

For the purge valve you will need to remove the round check valve and blow into the purge valve. Same thing goes for the turbo pcv valve. My shitbox is stutering for 1 second when i start it in the morning but i’m too lazy to check the issue for now.

I just wanted to check the purge valve, but now even with cold engine idle was very smooth.
Maybe the purge valve is about to get defective and was stuck open when I tried the first time.

Another thing I noticed: I can remove the hose on the left side of the purge valve without removing the green clip, this doesn't feel right, so maybe there could be a leak.
Maybe the first time I tried the purge valve was open on purpose but this leak was causing the problem?

I'll check it as soon as I have rough idle again.
I really appreciate your help!

Okay so I'm wondering if these external kits are available, I'm pretty sure my intake will need it... I looked in there the other day and didn't see the little red thingy... also curious about the hissing noise, where does the hissing noise come from? Mine sounds like it's around the intake and only does it under boost pressure... turbo was replaced a few weeks ago and developed a boost leak and throws a p2261 code.

If it hiss check the vacuum hoses. I replaced 1 already since it was hissing aswell and planning to replace all of them since they can be replaced wihout needing a mechanic.
Is just that i don’t have any proper low gauges hoses shops in the city so i’ll have to look over the internet for the correct size and guess what? I’m lazy for a job like that atm.
