While I'm driving my car, in every gear I hear a whistleing sound right after 4000 rpms. It sound like a mini blow off valve. I had my mechanic look where the sound was coming from and he can't find it. Does anyone have this same problem?

korney

hey, I have a weird whistleing noise too, I think that it might be an exshast leak or something. I'm haveing it checked tomarrow. but yeah I think that it might be a leak somewhere...

Coroner

Good to hear man. Let me know what your machanic says. Thanks for your reply.

korney

no problem man, honda-tech is here to help

korney

oh btw. do you have any mods done to your car? do you have a header? or something, cause if you do maybe while putting it on, they didnt tighten something up good, or something pinched your pipe and there is a hole or something...just a thught..

Coroner

Well I have stock hearders bacause I don't know whats the best headers for my car. But I do know for a fact that the noise started happening after some guy fell asleep at the wheel and crushed my right front fender. I think it might of damaged some thing by the intake box. Not sure.

if you have an aftermarket intake its most likely is the intake. when i put my aftermarket one on it did the same thing. shouldnt be a problem though, just means its sucking in more air. and it got even louder when i took my cat out.

Coroner

my mechanic says it might be some kind of air pump. I've got all stock parts on my car so its weird that I hear this whisling sound.

By the way I don't want to post a whole new topic over this but, what is the safest way to clean my engine? I was putting degreaser first and then power spraying it with water but i don't think thats very safe. I'm thinking of using a steam cleaner, like the ones you buy at walmart for houshold cleaning.What do you think?

M2B4

mine does it but its my intake. as for cleaning your engine follow the directions on a can of engine degreaser. dont spray electrical parts

maybe its your turbo

sportyaccordy

It's the broken intake. I have an intake on my Accord and it whistles like a ****. I kind of like it though.

skunk2 IM?

Coroner

is it ok to use a house hold steam cleaner to clean my ingen?

98vtec

is that possible?

darockstar

i had that same sound once my egr went bad...im pretty sure its a egr....but if ur car doesnt flip a code then i dunno????

Some people have come up with some interesting & possible ideas. One more possibility is the throttle-body. My Prelude made a whistling sound at some RPM at a certain level of throttle. I concluded it was air flowing through the t-body in just the right way to make a whistling sound.

korney

yeah, well the shop says that it might be the tb, or becuase i have a header and there is a lot more air being flowed, but there is not leaks, holes, nothing. I went with a drive with the macanic and he can here it too, but he says that it might not be nothing surious. At first, they thought it might be the intake, but I knew what it sounded like any ways. So yeah, it might be becuase of the accident, but just make sure that there is no leaks or anything, if not, then everything should be ok.

tytyguy

it could be an invisible turbo......

does it go away if you step on the gas harder? if so, it's the throttle plate.

not to steal this thread, but, yeah, when I step on the gas harder, it does go away. What can I do to fix this?

Siegfried

It comes from the screw on the throttle body on the passenger side , it makes the air filter wistle.
What is that screw for by the way ? an uncle told me it was to tune the idle.
The sound should stop if you unscrew it a little, you can mark you old setting so you can put it back if it doesn' t change.
That's the way I fix mine don' t know if it's the right way

Coroner

Cool. I'll try the idle screw thing and see what happens. But sorry if i look stupid but what the heck is a EGR? I'll let everyone know what happens tomarrow when I try all this. Thanx for all the good replies

hulk_22

it's probably your intake, double
