Okay so I was late for thanksgiving supper this weekend and caught a rabbit going 170 km/h on my highway so I matched his speed for the 30 mins drive...then after that my clutch felt like it wasn't engaging until i pushed it in quite far....like it felt really light until it was 3/4 the way in.

Then today I drove home to my city 2 hours away and it worked fine until I came into the city and went to take it out of 5th, I pushed in the clutch and it did nothing at all. I tried downshifiting and the clutch just wasn't there..but i rev matched and down shifted and up shifted a couple times, pumped the clutch a few times, and got it back to working just being soft for the first 3/4. It's not slipping at all In 5th going up a steep hill at 80 km/h it won't slip or anything..so I'm lost, any help would be much much appreciated!

 

your clutch cable might need adjusting, if you have one. this use to happen to a friend of mine a lot.

 

what kind of car and engine? it almost sounds like you have a hydro tranny and you might have a leak somewhere. but first lets establishwhat you got going under that hood

 

It's a 1993 Civic Si with the 1.6 Vtech (z6) and 5 speed manual tranny.

 

The clutch is linked to the clutch pedal thru a hydraulic system. First thing to check is the level of fluid in the reservoir on the firewall.

 

But if thats low I have a leak somewhere...I was trying to decide if it could be my slave or master cylinder..I know the slave went on my 300zx?

 

Exactly. If you find it is out of fluid, look for the leak. If it still has fluid but the clutch doesn't release, it can be a bad master cylinder or (more rarely) trouble in the clutch mechanism.

 

Ok so yes it was low..is there supposed to be just a loose little cap in side the res? I think it's leaking down into my interior from where the pedal goes into the master cyl..the hose from the res in the engine bay looks dry, just isnide where the rod goes from the clutch pedal into the firewall its leaking a bit there. Just need a new master cyl do you figure?

 

Yes a new master cylinder should fix it. You might also pull back the boot on the slave cylinder and see if there is any sign of leakage there, if there is consider replacing both cylinders while you're at it.

There is supposed to be a loose rubber piece in the reservoir, it would float on top of the fluid if you had any. I think it has something to do with trying to keep the fluid from absorbing water.

 

Great thanks, I just moved to a new city and don't have my service manual with me...any idea on where the bleeder valve is and which bolt i turn to open it?
