I've gotta b18c1 in my EG. Every once in awhile when I start my car (when it's in neutral) it won't go in any of the gears at all. When I start my car when it's in gear, my car moves like the clutch is engaged. Now when the car is off, it goes into gear with no problem. I just flushed out the whole clutch master cylinder, but the problem still occurs. I'd appreciate if anybody can help me to why this problem occurs every once in awhile. Thanks in advance.

 

Next time it happens, have someone push the pedal while you watch the throw-out fork moving. It should move about 12 or 13mm when you pump the pedal.

If it doesn't move, you need a new master or slave cylinder. Further testing might determine which, but lots of people will just tell you to replace both together anyway.

If it DOES move properly, then you've got something sticking in the clutch. Pilot bearing seizing? Clutch disk warped? Clutch disk with broken spring? Gotta take off the tranny for any of this stuff.

 

Thanks for the info. Where exactly is the throw out fork? This is a fresh motor with approximately 25-30k miles on it and the clutch still grabs real good. I'm sure JimBlack has already named off all the symptoms my tranny has ran into, but if anybody else has had the same problem I'd appreciate it if you share any other info that you might know, that will or might help me out to further diagnose this problem.

 

Bump for the night

 

Clutch slave cylinder is on the front of the bellhousing, kinda mid-elevation. Not sure about EG, but on my Integra it's real close to the right-side radiator fan motor.

The slave cylinder has a piston rod that pushes against the throw-out lever (or fork). This lever goes into the bellhousing, to work the clutch. There's probably a rubber boot over the lever - gotta pull that open to see the lever working.

 

is it a new clutch or old?
is it hard or soft when you push your clutch pedal down, if its soft then you have an internal leak (clutch master cylinder or slave cylinder), but if it's not then you have a bad clutch. It might also cuased by there is some oil on your clutch disc, flywheel, and pressure plate due to the main shaft seal and the input shaft retainer seal are bad, or you might have a worn disc facing, warped pressure plate, and broken diaphragm spring.
