I've been searching around for a boost leak for a while now, causing slow spooling and general lack of power.
I've pressurized up the intake to about 12psi and found a few small leaks but nothing major. If i pressurize to 12psi, it will slowly drop about 1psi every 10 secs till about 4 psi, then it will take longer. I can hear some air flowing somewhere around the head. Sounded very much like it was coming from the spark plugs, so i checked them and 2 bubbled a bit of water, but a little tighening and it stopped. The noise is still there, most prominent if i put my ear around the spark plug valley, but still very hard to get a direction on it. Im almost certain no more hoses are leaking, so where else could i be loosing pressure?
Thanks
