Gday. Ive installed a vx ecotec. The motor didnt come with the plenum where the throttle body comes with so i used my ecotec vs one. Now ive got a massive vac leak. Ive noticed the the valley intake that the plenum bolts to the vx one has a groove cut in it to yhe pcv valve and the old vs 1 doesnt. Do i have to go get a vx plenum to makw it all work? Or just replace the whole top of motor to the vs stuff which i have and would have to do a valley gasket, also the pcv spring is missing, is there a way around that or just find another spring and replace. Sorry for the confusion haha made sense to me. Cheers in advance
