Mein Auto: Z4 M Coupe 6LL93033
CDV install and clutch bleed

1.3mm: Smaller yet versus the 1.7mm we are used to seeing.

Tools I used.

Also used a second clamp on the reservoir clutch line output.
No leaks this way at all if you don't shake the hose.

Some other lock valves:


Clutch Bleed:

The E36 and E36/7-8 (Z3) use the same basic clutch pieces parts.
For some reason the E36/7-8 (Z3) cars engagement point is lower than the E36. On the E36/7-8 (Z3), the engagement point lowers with heat.
From checking out the E36/7-8 (Z3), developing the front shifting arm bushings, I know that the temperature in the tunnel area exceeds 200 degrees F. The stock front shifting arm bushing in my M coupe turned to mush in less than 5000 miles.
The clutch slave cylinder is in the tunnel area.
Bleeding the clutch raises the engagement point on some E36/7-8's.
I purchased the bleed tool to see what the result is using it. Will be checking this out later this year.
For the ingineer fluid folks, how would the engagement point change with air in the system versus no air in the system with heat?
In other words, is it a bleed the air out thing?
