Since most vacuum leaks come from cracks in the rubber vacuum hose where it
attaches to nipples in various places (okay, guys, wipe those weird images
out of your minds!) you can take any of the common approaches:
*buy a bunch of vacuum hose in all the sizes you see under the hood and
spend an hour or so replacing them all. The cost is reasonable and the
benefits are lasting.
*feel near the end of each hose for cracks and replace or trim the cracked
end from the bad one(s). Repeat next time there is a vacuum leak.
*if you can hear a whistle, try to isolate it. It isn't easy, but combined
with the change in pitch if you get your finger on a crack it may pan out.
Repeat next time....
*buy a vacuum pump/guage combo - about $30 US IIRC - and see which hoses
that come off the intake manifold hold vacuum. It is also possible to do it
with the suck to draw a vacuum and place your tongue over the end to see if
it holds, but that is really the po' boy's method and can get you an odd
reputation. Repeat next time....

I had a leaky vacuum-advance diaphragm on my Accord's distributor that I
didn't know about because it wasn't audible like a leaky hose tends to
be.... I found it by pinching off the vacuum hoses (gently, with
non-serrated pliers) one at a time until pinching one caused a
noticeable change to the engine sound, speeding up a bit and smoothing
out. Start where the hoses come off the carb, throttle body, and/or
intake manifold with this one, and if you find one that has an effect,
you can move outward from there.

That's a unique method. It's far superior to the method that I learned. We
learned to remove each vacuum line and pinching off one end while we
blowed into
it as hard as we could. They now have a device called a "vacuum/pressure
tester" that makes it easier. However, you method would work in some
cases.

I'm going to try this method. What size hoses do I need for a 94 Civic VX?

We could give you a lot of inaccurate answers and maybe an accurate one ;-)

Just do a quick survey under the hood, even take snips of the ends of each
different sizes you see (should only be two or three sizes) and estimate the
total length of each size. The hose is sold by the foot, so you'll want to
do the "Price is Right" thing: buy at least enough, but try to go over by as
little as you feel confident about.
