Well I drove the sephia yesterday for the 1st time in a month or so. getting some work done but anyways
At first I heard a ticking noise. comming from motor. Didnt sound good actually worried me a bit. Looked at oil a little low but not to the add line.
so i added oil drove to store still have this ticking. my first thought is lifter stuck gone whatever. go in store come out start noise is gone.
phew.
But this other noise is something that has been bugging me for sometime.
NO one seems to know waht it is.
I know it has to do with the clutch as whenever I push it in just a little the noise goes away.
Its a high pitch close together ticking noise. not same as above mentioned. this is in clutch the other is in motor.
I just want to know what it is or what you others may think it is.
Its not a huge worry for me as Im getting a new stage 2 clutch in a very short while.
what you all think?

I would think the clutch bearings, if they still have them. Last time I reassembled a clutch was an old Hillman Hunter, but normally when you half clutch you take pressure of the bearings, you should be able to feel a fine grind under your foot. Hope this helps.

Yea, i guess then you call it throwout bearing. It is not a real grind, it feels through the pedal though, I am not sure how to explain it better.

The throwout bearing really only gets used when you push the clutch in. The only noise it could be making with the clutch not pushed in would be the bearing rubbing on the shaft that it slips over. It should have grease on the shaft, but that could be long gone after years of use. The only other bearing in there is the pilot bearing (or bushing) which goes in the back of the engine where the tranny's shaft slips in. That is spinning with the engine even when you're stopped, so it could make noise, but I don't know how pushing in the clutch a little would make it stop. Make sure you replace both of these when you throw that new clutch in, cuz yanking the motor or tranny is a lot of work and one or the other needs to be out to replace them so since it's going to be apart, why not? Good luck. :57:

I had the exact problem happen on my truck. A 1972 Chevy C20. I simply adjusted the nut that sets the depth of the clutch forks when the clutch is not engaged. 3 turns of the screw was all it took. This happened right after I got the clutch redone.

I would look for a similar solution on the Sephia and look for a fine adjustment mechanism somewhere. It sounds as if the clutch is wearing and it needs to be adjusted for.

If that doesn't work, you can always try and exorcism.

1fastkia,

Is the high pitch sounds.... like some rotating noise ?
My guess is the Clutch release bearing is giving the noise.
When you next change the Clutch make sure you also change the bearings.
If it is the clutch plate fingers then you will hear a grinding noise when it comes in contact with the bearing.

Hope it is my guess .
