VACUUM IN THE HEAD...>I NEED REPLYS!!
does anyone know why i have vacuum in my head...i got a 1992 integra with ls/vtec and it has alot of vacuum in the head...its sucking in instead of blowin out
thats your crankcase ventilation. I believe you are talking about the hole on the valve cover. thats normal, just hook it back up into the intakes hole so it can filter the ait that is coming through it
