this sounds funny to me. but anyway stock head what an 8 valve non vtec. or what. i guess it doenst matter. i pull my wg ref line off and it goes up to one bar. but thats ok. its internal. i think we have all got the response that we needed form this guy.

wg spring can go double with mbc and bov can casue a "boost" leak without knowing. among other things leaking pcv and head gasket or intake gasket or even mani gasket, we cant see the car and therefore cant help em out on this situation.
