Ok I did a boost leak and all the air went through the entire intake system and bled right out the whole at the top of the valve cover. I was wondering if this whole was normal or if air is supposed to come out. I checked on 4g63 engine pictures for evos and that hole was connected to a hose. Could this be where the boost has been leaking?

 

i dont think ... thats where ppl put the breather thinggy or the oil cash can. but nothing to do with boost
