I just replaced the clutch and flywheel in my 1994 civic coupe about 2 weeks ago. after driving about 20 min it starts to slip. i've replaced numerous clutches and never had this problem ! does anyone have a solution to my problem? please help.

 

You may need to adjust the clutch pedal linkage so the master cylinder comes all the way out when the pedal is up. If it doesn't do that, hydraulic pressure will build up and the clutch won't stay fully engaged. To test that, drive for the 20 minutes then crack the bleeder bolt to see if pressure comes out and the slave cylinder moves. You should then be able to resume to drive (for a while) with no slippage. It could also be a blockage in the master cylinder.

 

i appreciate the help i'm going to try it tomorrow.
