    i traced it down to the vacume line from the intake,my issue is that it is sucking air threw the valve cover gaskets. i put a vacume guage on the line and it idles at 35psi and when you rev it up and on the down rev it hits 70 psi, i have never seen that much vacume 25-30 is the most ive seen even on the down rev,any ideas on why i have so much vacume, it is trying to such the motor inside out. lol
