[likoulou31]

Hi everyone,

I have a noise I can't locate on my Toyota Yaris 1.3l 2NZFE from 2001.

I can hear it :
- With any gears.
- Clutch engaged or not.
- Around 2000rpm
- Located in front of the car.

Here's a video :

Hope you guys will have a solution

Check the manifold heat shield. They eventually rust out around the bolts

I checked it and there's no rust on it.
Around bolts there's no rust too.

Intake manifold diaphragms loose?

[likoulou31]

Where is it located ?
It's the intake gasket or something else ?

ballast vibrating on frame?

id bet its just something thats loose and vibrating on something metal

[likoulou31]

What is the ballast ?

It seems to be located under the gear shift lever. I checked yesterday but found nothing loose

Ballast would be an aftermarket item if you had HID's.

If below shifter maybe a coin dropped in there somewhere?

Today I tried to make the noise happen again.

Parked I pushed the clutch pedal so no movement in the gearbox, went to ~2000rpm and I heard that rattle again.

Then I just pushed the lever shift downward and the sound stopped at a certain position between "no gear" and 2nd or 4th or reverse...

I don't know what it can be do you guys have an idea where to look ?

Hi everyone,

Could it be forks in the gearbox or the mechanism that control these forks ?
