So a couple weeks ago my GF and I were running some errands, the car/engine/etc was quite hot after 3+ hours of stop and go, in and out of several places. Well, after the last stop when i pushed the clutch in I heard this strange clicking sound. I could feel it in the pedal as well. I got home, took a look around and couldn't figure it out. Next morning it's gone.
I change the fluid and re-bleed the lines and everything feels and sounds fine.

then yesterday, same thing, we run some errands, and after a bunch of driving around on city streets, etc, it starts doing it again.

Then this morning when i go to leave her house, nothing. It's gone again. It seems to only happen once the clutch system heats up to what I would consider higher than normal operating temps. My normal driving to and from work is mostly highways, and I usually only have 1 or 2 days a month that I run the car that much on city streets to hear it.

When my friend josh tried to help me locate it, it sounds as if it's coming from the clutch master cylinder itself. Almost as if the piston shaft is catching in the pump assembly or something. You can hear it under the dash, but if you pop the hood and listen at the cylinder, you can notice it's a lot louder.

Anyone else have a similar problem or suggestions??
I have also noticed that only after a couple weeks, the fluid is quite dark again already. It's strange and really starting to worry me. I HATE dealer mechanics and would rather fix it myself if possible. I consider myself pretty savy when it comes to Honda's, afterall I have never owned anything else. But i'm about to loose all hope.
Any help would be appreciated.
Thanks.

Which fluid is dark.... the hydraulic fluid? Or your transmission fluid?

The good news is that hydraulic clutches are really simple - master cylinder, slave cylinder... and that's about it... so it shouldn't be too hard to figure out what to replace (if it comes to that).

There was a thread a week or so ago about greasing the actual fork that sticks into the transmission.

It doesn't sound like that was the same problem you're describing - but lemme see if I can find the link for you...

 

Yeah... here you go:

The hydraulic fluid is dark. Really dark considering it was changed just a week to 10 days ago.

That's an interesting problem as well, but I don't think it's what I am seeing. I will do that and see if it helps. Mines sounds and feels as if it is at the master cylinder, not being transfered though the line from the fork. I sort of find it hard to believe that a problem at the fork and slave cylinder would be transfered through the rubber and hard lines to the master cylinder and create a feeling and sound like it is sticking itself, but I am no expert by far, just like to think I am sometimes.

I can actually feel the master cylinder clicking, and for some reason I don't think this is the problem. Not to mention if it was the fork needing some grease, I think it would be doing it all the time, not just when it gets hot.
For instance, it's not doing it today and since I barely drove the car today, it never got hot enough to start again.
I will try this "fix" and see if it works. Time will tell.

Thanks.
