Help identifying these sounds

[cobra940]

Hey everyone, hoping to get some help here. I took the cobra out yesterday and noticed that it started making a ticking and squealing/chirping sound when it was idling. I'm not sure what's causing it and did a few searches on here to try and help.
At first I thought the ticking was an exhaust leak but everything looked fine when I crawled underneath and It seems when I engage the clutch the sound goes away.
I'm going to try and get it on a hoist this weekend to further investigate but hoping for some input/direction on your thoughts.
Possible it's the Throw out bearing?
Here are 2 videos to show the sound.

Cobra has minor basic mods with just over 14,000 miles



Apologies for the seatbelt alarm ringing in the second video

2nd vid sounds like TOB. Does noise increase with rpm or no?

Thanks, I'll look into ordering a throw out bearing and sleeve. It just started so I'll see if it goes away or if it's sticking around.

Use a ford bearing..

Oem sleeve is known to break..

I got mine from tremec out of dallas,
It's a 2 piece sleeve..it has a second collar piece that fits behind bearing.

Car had 40k when it snapped

For the top video noise I recommend using a stethoscope to help narrow down the location. A stethoscope helped when I thought I had a rod knock on my '99 but luckily it turned out to be a lash adjuster.

That's a good idea and i will look into that, its weird though because the ticking sound also goes away when the clutch is engaged.

really? Can you do a second vid showing the ticking sound disappear when the clutch it pushed in? Very odd...

I found a video of a 6-cylinder car that make a knocking/ticking noise with a bad TOB. I'm betting that both of those videos indicate a bad TOB. Post a follow-up after you install the new TOB.

For sure I'll try and get a vid uploaded this weekend

That gives me a bit of relief, (I guess I should have posted this in the "driveline" section)
I will definitely update this when I get around to swapping out the TOB. May not be for a few weeks though. Thanks for your input Bob

Here is another video, I laid my phone on the ground but you can hear the ticking appear then disappeared once the clutch was engaged (clutch was engaged around the 17 second mark then engaged every couple seconds) there didn't seem to be a chirp noise this time.
