Hi again.
Thank you, I assume that my drive is proportional to how much this is driving me crazy.
After further inspection I can also now see some fluid next to where the VCG is 🙃
I've taken a few videos and I assume this will help visualizing what I'm trying to explain in a second language.
Regarding the high pressure lines I've already had a mechanic friend of mine checking them all for tightness, he said they were good. But maybe I should try it as well.
Also this is the first time I tried it, but smoke also comes out of the oil filler cap. Which makes it harder for me to understand.
I'll be replacing the the valve cover most likely now. But I'm pretty sure that won't solve the problem.
Here are the links to the videos I've taken. I hope they help.
