Is that a t-jet ?
"Sometimes two quick sounds sometimes only one", sometimes none ??

Multiple possible culprits (in order of complexity/cost):
-accessory belt (old dry.. slips a bit)- replace belt
-starter motor sticking ( the pinion doesn't disengage fast enough)- take starter out take apart, clean with alcohool.. let dry, reassemble. put back in.

On the accessory side:
-alternator/alternator free wheel
-other rollers in the accessory belt
-water pump.
-timing rollers.
-clutch throwout bearing ( but i think it would also squeel after starting)
-dry cams..etc


Try this:
-remove accessory belt.
-start car
-does it still sequel?

Are you sure it's from the gearbox side?
I do have a feeling it's the starter... as you can see the engine speeding up a bit after the sequel. ( but could still be belt related.. as after it gets to idle speed-after sequel the alternator will output some more current )
 
Hi Aurick,

already asked Omer at 1st post to turn ON consuming accessories but the squeek did not increase so I guess it's not belt related, don't think it has anything to do with pulleys or rollers either, starter seem a better candidate; pinion not pulling-off fast enough would sound like this, but how could it be twice ?? Anyway, removal and a good clean will not hurt and maybe bring the solution...

Hi.
Thank you all for the answers :)
The accessory and timing belt is new, also the water pump.

Ill give the starter option a shot.
Ill try to clean the starter at the next weekend :)

Btw it sometimes does not make sound but that happend after the engine is warm and at ignition after few minutes of idle (get out to buy a beer or something like that) , but its a bit rare

Thank you all,
ill keep you update.
 
So does it happend with cold engine or only when it's warm, or is it NOT making sound when the engine is warm ?? Ignition after few minutes idle... do you mean you let the enigne idling, then stop and start again ?? I am sorry to ask that but the description you give is quite blury. Could you possibly record more clips with different view point so maybe we could identify more precisely the sound origin ? Please also remove any ratling cover/stuff, that doesn't help !!

Ill make it simple.
Cold start -> 100% Squeak.
Warm start (turn off the engine and leave the car for few minutes like the example i gave with buying something from a store, come back to the car and then start again)-> 70% Squeak.:)

Tommorow i will record from inside the car and from the left side of the car where the accessory belt rolling.
 
Hi Omer,

it's much clear like this, I was wondering the meaning of "Ignition after a few minutes idle..."
Please record as close as possible to the starter motor, behind the motor, underneath the air box / manifold, clutch / gearbox side.
BTW: pulleys and belt(s) are on the RIGHT side of the car ...

Regards, Bernie
