So my friend cooked his gtc 1.6 turbo and ive just stripped it got head skimmed and rebuilt with new gaskets.
The engine starts but soon after it starts to run a bit lumpy. I can rev is but hear a slight miss.
Now i am not sure why this air hole is in the rocker cover but i can clearly hear it sucking air in. And if i put my finger over it it sucks it in.
Can u tell me if this is normal please?.
I have included a picture of the vent and a video for reference. If u have any clues as to maybe i have some one way valve blocked from the mayo deposits from the hgf maybe?
I am not sure if the air and rough idle are related but any help is appreciated.
Ideas please. Thanks. T

Small addition to above. So if i remove the oil filler or the dipstick they both are under vacumn? Seems something is blocked i assume to create this vacumn. I am assuming the head is sealed or it would be blowing out not in. I cant see any water drop or further oil mixing with water but it is early days.

So i have removed the crankcase breather pipe. It is sucking like mad for some reason. If i remove it its sucking more air down this pipe than the air intake lol. Is there a one way valve like a pcv? I have read its meant to have a slight suck to remove gases and stop positive pressure spreading the gases out the filler cap or shooting the dipstick out but this is really strong.
