Strange Tube and Clutch Problems

[siguy8]

There's a strange tube sticking up in my engine compartment and I can't figure out what it's for. It's the one with the white cap that seems to have a vent valve on it. It's in the middle of this picture:



My problem with it is that the other end isn't connected to anything. I thought it went to my clutch, but I found that hose and confirmed that it connects to the clutch. The end has some sort of metal elbow on it. What is it?



I'm also having trouble on the correct procedure to bleed my clutch. The pedal only seems to have the lower half of the normal range of motion and it feels a little soft. Any direction on that would be great. I think the previous owner just replaced the clutch master cylinder.

if i remember correctly that is the vent for the front axle but if i'm wrong which does happen occasionally somebody please correct me.

Axle ventis correct.

I bleed the clutch. Just like I bleed the brakes with an assistant.  Pump 3x hold, open valve, shut valve. Repeat until no air is coming out

Axle vent... I'll have to find out where on the axle that came from then. That'll be a good project for tomorrow along with correctly bleeding the clutch. Thanks!!

mud kicker is right on. i beleive my vent tube connects on the top of my axle housing. i looked at it to check it a couple weeks ago.

Bingo and it has a 90* bend that points to the driver fender well

Bled the clutch and it still doesn't work. It feels like the pedal isn't giving me the full travel. What else goes wrong with clutches? I don't have any money, just patience and a strong desire to fix it, so I'm up for trying anything before taking it in to a pro...

When I bled my clutch, I held the slave cylinder IN while I was working the master cylinder.
Make sure that the reservoir does not run empty.
Also, check where the clutch pedal is connected. Is the metal spongey?

So it turns out that the connection between the pedal and the rod going into the master cylinder is wonky. I'll have to pull that out and bend it back into shape and maybe get a new bolt to go in there. Fun stuff.
