He half-way solved noise no. 2.

Noise no. 1 is still there.

While the clutch pedal is depressed, the release bearing is not rotating with the engine, so I think it's unlikely that the release bearing is causing the noise.

When you depress the clutch, the bearing should actually spin together with the center of the pressure plate. If it is worn out and does not spin properly, it wears out the diaphragm spring in the center of the pressure plate.

Here's a description from "How Stuff Works":

"Another problem associated with clutches is a worn throw-out bearing, sometimes called a clutch release bearing. This bearing applies force to the fingers of the spinning pressure plate to release the clutch. If you hear a rumbling sound when the clutch engages, you might have a problem with the throw-out.

[SIZE=+1]Clutch Diagnostic Test[/SIZE]

[SIZE=-1]If you find that your clutch has failed, here is an at-home diagnostic test that anyone can perform:[/SIZE]

[SIZE=2]Start your car, set the parking break, and put the car in neutral. [/SIZE]
[SIZE=2]With your car idling, listen for a growling noise without pushing the clutch in. If you hear something, it's most likely a problem with the transmission. If you don't hear a noise, proceed to step three.[/SIZE]
[SIZE=2]With the car still in neutral, begin to push the clutch and listen for noise. If you hear a chirping noise as you press, it's most likely the clutch release, or throw-out bearing. If you don't hear a noise, proceed to step four.[/SIZE]
[SIZE=2]Push the clutch all the way to the floor. If you hear a squealing noise, it's probably the pilot bearing or bushing.[/SIZE]

[SIZE=2]If you don't hear any noise during these four steps, then your problem is probably not the clutch. If you hear the noise at idle and it goes away when the clutch is pressed, it may be an issue in the contact point between the fork and pivot ball.[/SIZE]

You're probably right. But I think it could also be semantics.... the OP needs to confirm if the noise is heard WHILE he's stepping on the clutch or AFTER.

If the noise appears WHILE the the pedal is being depressed, that's the release bearing. This would be #3 symptom above.

But if the noise appears immediately AFTER the pedal has been depressed, that's the pilot bearing/bushing. This would be the #4 symptom.

The way I understood his post is that the noise appears when the clutch pedal is held down.

You're right. Dapat mas precise ang description.

mga sir ask ko lang sana about sa starex namin kasi pg narelease mo na ung clutch especially in 1st gear my sound na "GRRRRRRRR" hindi nman sy masyado malakas kya lng nkakairita pkinggan. pinapalitan ko n ung support nung propeller pero dprin nawala.pinatingnan ko na rin pero d mapin point kasi maririnig mo lang sy sa medyo kulob na lugar like sa garage. pag tinapakan ang clutch wala naman problem sk khit naka 2nd gear wala rin.maririnig mo lang kapag mabagal ang andar ng 1st gear. ayoko lng din kasi lumaki ang problem.sk baka abutan pako sa byahe.baka may experience na kayo or idea about that.maraming thanks in advance!

i had a almost similar problem..if malamig difficult to shift, my mechanic suggested that i replace the clutch assembly. i did and so far its ok naman.

my question is i hope mga experts can help give their views. i bought a seiken clutch master assembly. sabi kasi its a good replacement.
auto supply ask me if aluminum or steel, oem is aluminum. i bought the steel one coz its cheaper.
ano difference? which is more durable? somebody told me yung steel na clutch master mas mbilis daw mapudpod yung rubber sa clutch master.

please give insights. thanks
