Weird sound when engaging clutch.

I've been getting a really weird sound coming from the clutch (not the pedal but the actual transmission). It happens about 50% of the time when starting from a dead stop in 1st gear. Very seldom, it happens in 2nd when acclerating -- immediately as I am letting the clutch pedal up.
My best description of the sound is someone saying "hoo" in a high pitched voice. Like an owl with some helium inhalation!

What could this be?

2004 6MT, original clutch, 180,000km (about 112,000 miles).

I know what you mean. I used to have that in my integra. The mechanic diagnosed it to be a worn out clutch or something, can't remember. But I sold the car before I even changed the clutch.

As previously stated, its the throwout bearing in need of lubrication. This is a common issue on 6MT's (seems to be more pronounced with cooler temperatures). Fortunately, aside from the noise, it wont harm anything to let it ride like that. Unfortunately, to fix the issue, it's basically the same work as replacing the clutch...

Everyone suggests the clutch release (throwout) bearing but this confuses me. The OP describes the problem occuring only during clutch engagement. If the bearing is going bad, shouldn't it make a noise (usually a screech of squeal) anytime the clutch is disengaged? So, anytime you're sitting there with the pedal pressed, the bearing should be making noise. At least, that is how my bearings have acted when they failed.

To me, this description sounds like the noise is produced when the clutch disk begins to contact the flywheel and pressure plate. Noise is only produced when the clutch disk isn't spinning or is spinning at a much lower (angular) velocity than the flywheel and pressure plate.

That is kinda what I was thinking after more reading. It seems to make the noise at the exact time the clutch grabs and the car begins to move forward.
Could this basically just be a wearing-out clutch disc?

Would this have any relation to me having replaced the R axle (half shaft -- not the entire shaft to the transmission)?

The noise went away for about 4-5 days as it was damp/raining all week. Since it's dried up over the past 3 days, the noise is back. Does this still sound like something internal to the clutch/transmission?

Bout to drive me crazy. It's when I'm disengaging the clutch. I had my dad look under the hood while I got the car to make the noise and it's coming from where the cables attach to the transmission housing. Is slave cylinder a possiblity? I brought to a transmission shop and the mechanic told me it was a broken spring in the clutch disc but I'm not so sure about that. Just dont want to blow the money on a clutch and labor if not necessary. I will try to have a friend who works at Honda take a look sometime next week and I'll post what he says.

The problem hasn't happened, at least not that I've noticed, in a month or so. Maybe because it's been fairly cold here, I don't know.
Car is in the body shop after a snowplow truck backed into my fender/hood/headlight but I should be back in its drivers' seat by Friday. Currently, the Kia Soul rental I have is making me REALLY miss the TSX. What a POS this thing is!!

No worries, I'm getting "fish" JDM headlights and a fully repaired and repainted bumper and OEM lip in addition to the new hood and fender from insurance. ;) And to think I was going to have the hood repainted this spring for $500... or I can just pay my $500 deductible and have all of this new stuff and other things done. ;)

Why are you paying YOUR deductible if it was someone elses fault? Shouldn't it be their insurance?

Had this happen in my 04 w/ 125k recently. Only seems to happen when its cold/damp and on starting in 1st or sometimes 2nd gear, as if riding the clutch while giving it some revs, is what it seems to do. I assume the TSX has a check valve in the slave cylinder similar to the s2000... which i know is popular to "delete." Wonder if that is part of the problem, its not letting go of the clutch quick enough, more or less. Have not been able to get it to happen on downshifts at all.

My '04 started making the same noise at about 100k miles. Very intermittent at first, two years and 30k later it is starting to make the noise very frequently. There are lots of hills in Western PA and it seemed to first occur only starting up a steep grade, it has slowly worsened and in the last few weeks it doesn't take much of a grade to generate he noise. I have managed to keep the noise to a minimum by using my parking brake. When starting on a hill, I keep the release button held down while I pull up on the brake arm. Don't let the car drift back, then as I release the clutch, lower the brake. The whole goal is prevent the car from drifting back and putting additional pressure on the clutch - simulating a level road surface. Mine doesn't squeak when I do this, or I should say didn't, it's starting to now, which is why I am going to be done with it and have the clutch replaced.

I have not seen anyone report a known exact cause, although I have read that people said a new clutch and t/o bearing kit fixed it. Either way, there is no easy pill for this one. The only way to assess the issue is to pull the transmission. I believe the estimate to R&R the trans is 8-10 hours of labor. Every situation is a little different, but my odometer is 130k, so it would be a mistake to spend $750 to $1,000 and not replace the clutch for another $300. These cars are really reliable, so I am confident that my car could easily see 200k.

I will try to remember to update the board, but my guess is that the answer will be what no one wants to hear.

This issue is to do with clutch release bearing, and it is common. It is annoying, but PITA to replace as it takes clutch job to get to it.
Only ever use OEM one when you are replacing these (when changing your clutch) and even with OEM your mileage will differ. If you decide to replace one of these, do the clutch at the same time, it just makes sense for the $ you will spend to pull the tranny anyway.
Mine is howling for 75K miles now, so other than annoying it has a lot of life left in it from the onset (it would appear that other people share this experience).

These take a lot of pounding in doing what they do, and unfortunately there are no perfect solutions, new OEM might give you "howl" after 25K or 100K...

Update:
Just found another issue that produces this noise, especially when loaded (as in first gear) taking off on an incline, and it gets more pronounced colder it gets outside. This noise comes from the flywheel bushing, the little one where mainshaft goes into.

In short, release bearing and flywheel bushing should be replaced. Since both need tranny removed to do, it goes without saying to do both at the same time. I also think that this bushing is the bigger issue of the two as having mainshaft spin inside it makes me really wonder for how long can this thing remain quiet after being replaced. Ignoring the noise until the clutch job is recommended here, as there is no guarantee that replacing parts will permanently resolve the noise. For a while yes, but could come back in relatively few Ks.
