Chirping noise from engine bay

[mad in general]

Hello all,

Today I have noticed that there is a chirping noise coming from my engine bay. I can hear it when sitting at idle but as soon as I press the accelerator it disappears. It also slows down when I switch the ignition off and the engine is shutting down.

Any ideas at all?

To be fair I was going to say no smart arses.
Any real suggestions?

It will be aux belt related i reckon. Get it checked over.

Gutted, I was going to suggest that you needed a new cat

Ok mate, Thank you. Apart from obviously worn or ripped what should I be looking out for?

Don't they meaow?

I guess it'd keep the birds out though.

Parrot for myself there then.

it could be the thrust bearing on the clutch. Easy way yo tell is to push the clutch and see if it goes away. If so, you need a new one at some point (although mine on my mk1 has been going nearly 40Kmiles now chirping away).

I was sitting in neutral at the time and tried it with the clutch dipped. No change in noise.

Cheers though.

I had this it turned out to be the heat shield rubbing on the bottom of the exhaust manifold to the cat .

Ok so today I am going to inspect the auxiliary belt.

How do I get easiest access to inspect the belt and pulleys? What should I be looking for?

It seems that the noise is actually coming from the top of the gearbox. Directly under the factory air box there is a chirping/squeak noise. Any ideas guys?

Anyone have a bright idea as to what will be making this noise?

It doesn't seem to get faster with revs and doesn't feel like its affecting the drivability.

 

[mad in general]

Managed to get a recording of the noise.

Its coming from the gearbox area, doesn't appear to get faster when the car is moving.

Please listen out for a squeaking/chirping noise. All advice is appreciated.

Does it make this noise when you are on and off the throttle in stop/start traffic?

Any movement in the gearstick?

 

[GrahamS]

Has that got a V6 airbox?!

Could be contamination on the clutch maybe. Does it change when the clutch is in, out or mid travel?

Other things it could be is a loose gearbox mount bolt, exhaust or something with the starter setup. Have you tried rocking the engine with the engine off to see if it makes the noise?

Take the airbox and battery out and check the lower upper gearbox mount in the battery tray is tight.

Edit: didn't read above.

 

[Dan@SJM]

clutch release bearing.

 

[mad in general]

The noise is audible when driving and when idling, regardless of gear or clutch position. I have a poly dogbone fitted and theres pretty much no movement in the stick.

I have only just noticed this noise since fitting a ktec style induction setup for which I had to remove the battery. Possibly linked to that?

 

[The Fatty]

could be. check everything is tight.

 

[mad in general]

clutch release bearing.

Would this still make the noise whilst in neutral and pedal up?

 

[The Fatty]

thats when its most likely to make the noise! its has nothing to do with the gears / which gear your in.

I honestly have no idea. How would I find this out for definite?

Sorry mate didn't see that. I'm with Dan, clutch release bearing is most likely if it's from the gearbox end.

Just check the aux belt as sometimes if it's got a bit wet it could slip and make than noise.

Is there any way for me to tell for definite that it is this bearing?

 

[GrahamS]

someone else will know better than me I'm afraid.

Do you know anyone local who you 100% trust to give you an honest and reliable opinion. I'd go there as you really couldn't be much further from me on the same piece of land!

Sorry I can't help more

there's little else i could be at that end. Clutch release bearing or input shaft bearing are the only 2 I can think of the aren't covered in oil and would make that noise. Like I said before though in post #10, you can normally tell by pressing the clutch pedal as the noise generally goes away / changes when its under pressure.

Today I've had the battery out and checked the gearbox mount. The main bolt was nice and tight, 1 of the 2 smaller bolts was quite loose. All tightened up and reassembled. Unfortunately the squeak is still there.

The noise doesn't seem to change at all regardless of gear or clutch position.

I'm still hoping that it could be something else?

You say it doesn't matter if the engine is revving higher or at idle, it stays the same yea??

Maybe the slightest of differences but certainly not obvious. it squeaks until I shut the engine down. It is definitely passenger side to.

 

[l33th3tr33]

I'd listen to Dan, he knows his stuff.

Yeah I just really don't want to have to do this and once reassembled for the noise still to be there, just trying to double check.

 

[l33th3tr33]

I know what you mean, Will you be doing the work yourself? If so then at least you won't be paying labor.

 

[mad in general]

Yeah I will be trying it anyway. Have studied Budgies guide and I feel pretty confident. Fingers crossed anyway.
