I just put a new engine/tranny into my 94 civic. Straight d15b7 to d15b7. The motor's in and runs great but I can't get any pressure to build in the clutch. We tried bleeding it but it won't really build any pressure. We swapped slave cylinders from the trannies but to no avail. Any ideas besides the clutch MC?

 

did you put the throwout bearing back in. Friend of mine did that once.

 

+1

and any fluid leaks?

 

check under the dash to see if the piston inside the master cylinder is leaking, then also you may need to bleed that slave cylinder for a while, i bled mine for like over 30 minutes and it didnt do shit, then we bled it for like another 15 and bam it all of a sudden worked

 

WTF is that? lol, don't know too much about the clutch components.

How do I bleed the slave cylinder? We were just bleeding it like brakes, lossening the bleed screw and pumping the pedal.


Another thing I think might have happened is dirt got in the lines and is clogging something, because the fluid is filthy and there's no filter in the reservoir.

 

ya my accord is doing teh same thing.. id tryed everything.. no leaks.. we got lil pressure once but we tryed to bleeded it again but it went away.. now i can get anything!!!..

help! lol i need to get this done so i can go to the track!!!

 

clean the lines.......... check rubber gaskets around mc and then rebleed lines

 

Do you think getting a vacuum pump would help? I think I'm gonna rent one tomorrow to clear out the lines and start over fresh.
