ok i just swapped a head for im reasons the head was remachined about a year ago and has only had 200 miles on it (valve job resurface the whole 9)
well a year ago my crank seal busted and i spun a bearing. now i got the head on a new block today and same problem arises busted crank seal. could the head be causing this. and i think i have a vacuum leak somewhere. it idles at 1900 rpm with iacv disconnected.


and thanks to the guys who have helped so far with the previous post
