ABS pump over-cycling?

@dwtaylorpdx - this is a great idea because it sounds a lot like a fluid pumping noise / cycling noise ... I took the advice of pulling the ABS fuse just now though and continued to hear the noise.  It seems to becoming for just behind where the clutch master cylinder ends, possibly a bit lower than that.  Thanks for the idea, it’s one less thang I have to worry about and I’m glad it wasn’t a failing ABS pump!

Fluids, like solid objects, can transmit noise.  If the throw out bearing is going south, it can transmit that noise to clutch slave, and forward to the clutch reservoir, which is just on the opposite side of the firewall from the clutch pedal.

 

Put the car on a lift and listen by the bellhousing, if the bearing is bad, you should hear it.

@JFP in PA that definitely makes sense, I had crossed throw out bearing off the list because I’d read somewhere that it only makes noise when the clutch is depressed (my issue is when the clutch pedal isn’t depressed - and the noise actually resolves when the pedal is sent even slightly downward).   I’ll put it back in there though ... thanks!

In my opinion it has something to do with the thrust bearing, have this checked by a mechanic to be sure.

@RFM thanks - I’m reading up on the thrust bearing now, is it located in the rear of the vehicle in proximity to the engine?  The noise is emanating from forward of the clutch pedal (in the area under where the drivers side wiper blade is (roughly) but down low - basically right I’m front of the footwell.  I’m just trying to connect how the thrust bearing would make a noise in that location from so far back.  Thanks for any additional info.

The posting of your links needs to be cleaned up.  But, not sure how, I did see video and hear sounds.  
Bizarre.  Only thing that initially comes to mind is that sounds are somehow travelling up along clutch cable.  Not even sure that’s possible.  Is pedal secured?  Is cable from clutch ok?  I don’t think there are any pulleys in front of firewall.  Mystery. Good luck

@judgejon - thanks, new guy - so I’ll work on my posts, sorry!  The pedal feels secure and the clutch operates completely as it should - no slippage, grinding, leaking, rough shifting, any of that ... I don’t know the status of the clutch cable, I’ll have to add that to my list of things to investigate.  Thanks!

You had a hydraulic not mechanical clutch. Does the ticking speed increase if you touch the accelerator lightly? Is it there at any time while driving?

Johan

@UwonIt does not increase when accelerating - it can be heard while driving but only when the car is in neutral (I’ll admit that the engine noise may be concealing it in gear but I’ve not heard it while in gear).

 It is somewhat intermittent But becoming more consistent - I purchased the car in May and the sound was present every other week, a few months later and it’s there almost daily.  
 

it’s definitely originating from just behind the clutch pedal (by behind I guess I technically mean in front as the car points). 
 

car has 68k miles, clutch done at 31k and IMS/RMS/AOS dome by previous owner at 50k

Here’s another with just the noise ... 

Ok - 2002 C4S ... and I have a weird one here.

Does anyone have any idea what would make a whirling, clicking sound (almost like a gerbil wheel-like sound) directly from behind the clutch pedal?   The sound definitely seems to be coming from behind (forward in the vehicle) the clutch pedal and can be stopped by pressing the clutch very slightly (movement of about a centimeter does the trick).  
 

I don’t have any of the typical issues (that I’ve read about) for a failing clutch master cylinder, but I have to admit that just moving it slightly seems to make the noise go away.  Is there any kind of valve, pump, bearing that sits just behind the wall?  
 

Here’s a link to a video I made that shows the clutch action and you can hear the noise ...

Thanks for any advice!
