Need Help: Funny Noise From Front Of Car

[humble]

Hi all

Over the last few days I have heard a strange sound coming from the front passenger side of the car.

This only seems to occur under acceleration/ pressure.

It sounds like a rapidly tweeting bird or a rapid squeak (sorry of the bad description). It could also be explained as high pressure air having something waived in front of the flow.

When I had the 3in zorst made the guy said that there was a bolt missing on the zorst manifold. At first I thought it could be just leaking pressure, then thought it was the turbo but now I fear it could be something else. A mate just said it sounds a bit tinny to him….????

Don't have a clue???

Any thoughts???

stupid question...does the sound differ from the turbo spooling? happen at the same time?

Check all pipes for leaks? Could be a cooler pipe leak? Same with exhaust?

Or pinging? best way to describe pinging from me is like put a small stone in an empty coke can and shake it inside your engine bay...?

After asking a mechanic mate:

Could be something loose or broken and rubbing, like a motor/gearbox mount, or a tailshaft?

If it is only happening under load, then it is being caused by the load, or associated under load variables (eg increased airflow), or torque twist.

Not a stupid question

Yeah the sound is different to a spooling turbo…..The funny thing is it doesn’t do it all the time.... sometimes when I try to accelerate harder to hear it again trying to suss it out it doesn’t make the noise….

SKA

It’s not pinging, I know that 

I think you could be onto something about the broken or rubbing of a part but don’t think it’s a tailshaft or mount….

Definitely only happens under load but as said above its not constant….

Will get the bolt sorted on the manifold this weekend get new manifold also just in case and check all pipes etc… wonder if it could be the air box as I put it back in from having a pod in there???

Really stuck!!

Heres a stupid question… my charcoal canister is loud as a mofo… could it be playing up under load ??

[Ska]

Ummmm charcoal canister is just for letting the fuel tank breathe, so what do you mean by, "is load as a mofo... "?

sorry should have just said it makes a (loud) rattling noise

[AlexCim]

mine makes a trickling noise, as if air is getting past the hoses, which i am sure it is

Meh, cant do any harm.

sorry should have just said it makes a (loud) rattling noise

Could be not bolted down tightly, maybe? You sure it's the canister? Sounding more like something is definatly loose.

[humble]

yeah the canister definitely makes some noise

Alex can verify that....

Although the noise that makes when the car is stationary is different to this concerning one….

[Terminal]

Anyone thought about the climate control unit? this is located in the front passenger foot well. a belt or fan motor could be loose or have come away from something else. i'd dig around there and see if that's the problem

[Ska]

Yeah could be loose/slipping belts, good point Leshy!

I personally have never heard any noise from my stagea or my skyline canister, although I have never really tryed to listen specifically to it before either....?

[humble]

Thanks Leshy

will have to check this out....

might also see if any of the guys at the cruise on saturday have any idea....

Cyrus

mine is pretty loud and you dont even have to be looking for it to notice the noise....seems to be secured though so not sure why the noise??

[Ska]

Honestly I wouldnt have a clue, all I know is what I have heard from mates and stuff. Have been told that all it does is filter out the petrol vapour out of the air venting from the fuel tank so that it does not vent to the atmosphere....?

But hey I am by no means a mechanic, just offering suggestions...?

[humble]

thats cool man

apreciate your help

thanks
