im hoping its just my 5/6th ports working (since i just unstuck them) is this normal? i have a apexi intake.

 

Your aftermarket intake is causing the increased noise.

If you suspect a vac leak, a vac hose makes a good precision listening device.
Hold one to your ear and position the other end near possible leak noise sources.

BTW Russ - 4K$ is not a money pit - It's a bargain.
Did I say that once before?

 

alright i will check that just to make sure i dont have any leaks. yes i think you have. 4k is alot of money when your 16 and pay for everything yourself

 

pay for everything yourself? GOOD MAN!! way to be!

 

exactly! when ur young and have a job like mcdonalds ( moving to sears ) =) then 4k is a lot of money! i'm at about 3600 and that's way not enough yet! but that's like 75% of my paychecks!

 

i know what you guys mean. im 16 with a 1990 red convertible. its gona need a new engine really soon. it can be depressing

 

Well the intake on mine certainly makes the engine louder, and you notice it when you're going wide open and the 5th/6th ports open up...but I don't hear any whistling, just the wonderful rotary roar.

Good luck... you can always turn the radio up

 

It's your turbochar.... oh wait. haha

On a serious note, I had an exhaust leak that made a harsh whistle when at high revs.

 

Its probably just the ports or the intake, probably nothing to worry about mine whistled at high RPMs (and believe me that thing was always at a high RPM ) after I got a custom cold air intake and it just quit after awhile guess it just needed broken in.

 

check that the plastic muffler used for the ACV dump is still attached. SOmeimtes the rubber hose will fall off.

It is near your passenger side headlight. Look up the FSM if you still can't find it.

 

i might be wrong but i dont think acv's sound like a whistle

 

 

the whisle can also be a belt that needs to be tigthned. my car was doing that at 6,000 rpms and found out it was the a/ belt too loose

 

the ACV dumps air to ATM at a certain RPM. I can't remember what RPM exactly, but in doing so the stock system runs from a 5/8inch rubber hose to the plastic muffler underneth the passenger head light lamp. It is there so that you don't hear a hiss/whistling sound when it does this. If the rubber hose if off or ruptured then you will hear it dump to ATM.

 

I hear the depression part, I bought my T2 about a year and change ago at 16 and now it needs a new motor and tranny, I bought those but I work so much I can only work on it for about an hour a day, so it's gonna take a while to get it in. I work at a shop and ride a bike to work, everyone laughs at me :P Oh well, BMX for life.

 

I agree that it could be an exhaust leak. My friends' Dodge Stealth whistles like a turbo at high revs. He knows its an exhaust problem that happened from a twice botched repair job. He likes the whistle sound though so he hasn't taken it back to the muffler shop.
