vacuum leak
hey guys i just redid the head gasket, water pump, and fan clutch and i got the truck running, timed and its still making a squeeling/ whistling sound comming from under the intake manifold, i've looked and i just cant find it, its very frustrating, is there anyway to find a vacuum leak or what should i do, don't really want to take it somewhere and pay 100 bucks an hour to find it, anyways heres a link to the video of the sound http://www.youtube.com/watch?v=QmU3mCA36P0 and its a 1984 4runner 22r with a webber 32/36 carb thanks guys

Wow, that is a prominent whistle. My father-in-law is an old gm dealer mech, and taught me to use a vacume line to find things like that. You take a small vacume line about 2 feet long, put an ear plug in one ear, the vacume line in the other, and go around the engine. I have found I like that better than an stethoscope. Another way may be to take some break cleaner spray little bits at a time, in different areas, and watch for the engine to bog down, and look for were it is getting sucked in.
Hope it helps.
