It's a 1983 633 Csi with 220000 miles on the original engine.
The clutch pedal was spongy and I replaced the master and the slave
cylinders then bled the

system. For about 6 months I didn't have any problem then the clutch
pedal started to stay

on the floor and didn't come back. In order to use it again I had to
pull the pedal up and

wait about 5 - 10 minutes. When the problem showed up more frequently
I thought that the

parts were defective and replaced both of them one more time. These
new parts acted fine for

about 4 months and the problem appeared again.
I took the car to a mechanic. They checked the parts and found nothing
wrong with the clutch

hydraulic system and offered to bleed the system that didn't change
the result.

I wonder if anyone had such a problem in the past and how solved it.
Or does anyone has any thought about it.


Only two other things that I can think of are:

a) The clutch system (the pressure plate) has a problem and moving
somehow. By the way I

have 125000 miles on the clutch but it's not slipping at all.

b) The crank is moving back and forth moving the clutch assembly
together. This is a

known problem with some Mitsubishis but not with BMWs.

I would appreciate anyones opinion.

Thanks
Phil
