Title: Creeps like an automatic at idle
Post by: DesertEagle on July 29, 2010, 07:49:39 PM
Hey,

I rebuilt or replaced the calipers and parking brakes.  Before that the car needed a lot of revs to get it moving and was easy to stall.  My wheels turn much easier now.  I also replaced the clutch slave cylinder because there was resistance before the clutch engaged.  I found the slave heavily corroded.

Now the car is much easier to get moving, but when I give it gas the engine sounds just like it's revving in neutral.  There is some correlation between engine revs and speed, but not like there should be.  Also, the car creeps forward in 1st gear if I take my foot of the gas pedal just like an automatic does.  Is that normal?

Thanks for any help!

Sounds not right...like the clutch isn't fully engaging or disengaging.  Is the clutch slave bled properly?  It might also be hung up on some leftover grit in the bore.  Did you hone or clean up the piston & bore?

I replaced the slave cylinder.  I pressure bled the clutch.  The pedal feels firm.  I read a lot of threads on various forums tonight.  The only person with the same problem was letting their foot rest on the clutch pedal when driving.  I was doing the same.  Is that a no-no?  

Is it possible that the tip of my pushrod missed the hole and is resting on the lips around the hole?:D  I'm speaking about my clutch of course.  From what I read, if you miss the divot in the clutch, the pushrod is ejected from the cylinder when you press the pedal.

Resting your foot on the clutch will prematurely wear the clutch. You are basically riding the clutch! The creeping forward sounds like the clutch is already at friction point before you have actually moved the clutch pedal up. I suspect your clutch could actually be worn or that new slave cylinder is not doing what its supposed to.
