I have an OBD-0 DOHC zc in my 1990 civic si. I recently had problems with my transmission. I thought it could be the cable, so I replaced that, nothing. I took the transmission off and the throwout bearing was broke into pieces, I bought a centerforce bearing, put it on and everything back together and still does the same ****. My car does this:

1. The car will crank over and want to start when it's in neutral, but will not run.
2. When I push the clutch pedal in, put it in 1st gear, then try to start it. It jumps forward as if I'm not even pressing the clutch in at all.

Any ideas on what it could be? oh my clutch is from http://www.lsdmotorsports.com

 

Pressure plate

 

is the tranny any good?and what do u mean by will not run?

 

Well the tranny was fine up until last Friday when all this **** started happening. and "not run' I mean that I turn the key, it cranks, I let go of the key it shuts off. thanks for the quick replied people, keep em commin!

 

one of the teeth on the pressure plate was bent making it so i couldnt put it in gear while the car was running.

 

bent fork ? it's not disengaging right?

 

maybe a bad manishaft breaing.

 

I'm going to check the fork today and see how it looks. Any other opinions??

 

well since the throw out bearing was shattered I would make sure the preassure plate is on in the right direction!

 

What do you mean make sure it's in the right direction? didn't know it would fit on any other way..

 

Anyone else?

 

check and make sure the clutch is good if its jumpin while depressed

 

Would a really worn down clutch disc cause this problem? also is there away way that I can visually see something wrong with the pressure plate?
