OpelVectraC 2006r Z18XER 140KM - Damaged kzfr solenoid VC 1.8 z18xer valve,

Hello, in the attachment there are photos of the kzfr valves removed today, on one you can see muck, it was silicone, probably someone previously wanted to fix the broken mesh on this valve, only here it was dirty, as you can see in the photos, the valves were clean in general, I washed them extraction and put them in with back, I also recorded the sound when I start the car after installing them, can you hear the kzfr wheels, is this a normal sound ???? because I think you can hear a bit like diesel. The second thing is the valve plug, one broke and can it be replaced somehow? photo from the attachment.
In general, I want to take care of my car because I have already replaced the chest in it and I do not want to sell it because I do not want to buy something cheaper and I would have to add 10 thousand to the more expensive one, and you do not know what you will buy.
Is such a hole in the valve a threat ??? I am thinking of replacing both kzfr wheels and valves, only PLN 1150
I plan to adjust the valves because it has lpg and it is required. Recently, I replaced the valtek lpg strip with AC W01 and I have such errors:
0170 and 0014, I hope to get rid of them in a gas station in a few days.

recording and prior to cleaning

Today, while driving, I felt the smell of something burning from the airflow, after returning home I saw the puking engine with oil under the valve, I took pictures and it seems to me that some leakage occurred when I screwed the valve on yesterday, there are no gaskets there, only metal to metal .. ... or it's something else just a coincidence, the car will cool down and I have to wash it off to see where it is coming from ... the massacre is still going uphill !!!

so today I installed a new valve, I had a problem with tightening the screw, which was mentioned on the forum from the link, but I gave some small two washers and it kind of came to the end, it probably doesn't have to be that great, there it touches metal on metal so if it wasn't for the O-ring, it would fly thanks to the pressure, but I still think to thread it to 6mm and give a thicker screw. I haven't removed the mesh from the new one yet because I was afraid that something might be wrong with it and later I won't be able to give it back, then I'll throw the engine sound and a video, it clatters a little for me, but maybe valves ... maybe I'm oversensitive? from the link what you gave above the wheel was evident for me there is no such noise
My plan is this: I will adjust the valves soon, if necessary, with grinding glasses, etc., then we will see how it works, or I will buy a second valve, remove both strainers (2z3), change the oil and do a rinse beforehand ????, install a filter with a spout and we'll see how it goes again, at the end I leave the zfr wheels. Ps. I still have these two mistakes.
