Full throttle i had somebody crank till it builds much compression as can and put foot down and i also push throttle pully down

Test results

Cylinder 1 : 170psi

Cylinder 2 : 180psi

Cylinder 3: 170psi

Cylinder 4 : 170psi

Also for cylinder 2 i didnt push throttle pully all way down but was pressed from inside car

Okay as when i took oil cap off and gives out smoke/steam and it goes away.

But when i rev it, it does slightly give smoke unless its steam.

But results are okay so.

Only thing im thinking is what if on cylinder 2 if i held throttle pully down aswell it may be like 190 or something?

I didnt hold it down on cylinder 2 , only accelerator was pressed from inside

And for cylinder 1 it was 160 psi with accelerator down, but i did again with the throttle pully all way down it went to 170

Still got a PCV mate? Sounds like this as it is only open under vacuum and closes under boost. So if your getting excessive vapour come out the oil cap it would indicate your getting excessive crank case pressure.

No adam i have no pcv , just a race spec rocker and the both pipes of the race spec rocker are venting.
