Intake manifold whistle
does anyone know what would make and intake manifold whistle. i recently swapped an 92-93 civic vx manifold to a 90-91 crx si manifold. everything seems to be secure. however and a certain pedal pressure it makes an annoying whistle. does anyone know what might make it do that?

Did you use new gaskets and make sure all the vacuum nipples where used of capped? It may be a vacuum leak.
(Edit: I said "manifolds" instead of "gaskets." Duh moment, sorry.) |
thanks i will check that

(I editted my previous post, bump so you'll notice it.)

Its the manni itself. All CRX Si's do it(if its got an intake). If you want to get rid of the noise youll have to swap the manni.

my friends si doesn't. this is a high pitch whistle and it is only when i am giving it a certain amount of gas. i could be wrong but i don't think my friend's whistles i will check

I have the same whistle with my 90 Si...my buddy said if i got a Throttle Body spacer it wouldn't whistle anymore

sorry cant type apparantly
kai...... all of my vacume hoses seem to be fine and i can not locate any cracks or gaps in my manifold. is it possible the whistle is coming from my vacumes sucking to much or to little air? any suggestions.

mine whistles too, with my intke on it, with like 50% gas at around 3200 rpms.
