Hopefully by this coming up Saturday (September 20th 2008) I will receive the modified Clutch Delay
Valve for the Z4 so I will replace it.
More information can be found on this website:
From Zechhausen website:
The Clutch Delay Valve (CDV) is a one-way restrictor installed by the factory between the clutch slave cylinder and clutch master cylinder. It "delays" the engagement of the clutch, much like old record players used a damped tone-arm to gently lower the needle onto the surface of a record. Because of this valve, no matter how quickly you lift your foot off the clutch pedal, the clutch engages the flywheel at a constant (slow) rate. In theory, it can save the driveline from shock, were an inexperienced (or immature) driver to dump the clutch at high RPM. But in practice, all it does is prematurely wear out the clutch and turn experienced drivers into people who, despite 20 years of practice, cannot shift gears smoothly. During parallel parking maneuvers, the delay can be infuriating, causing constant clutch slippage. And during hard acceleration, the large amount of clutch slippage can greatly shorten the life of your clutch. During normal, sedate driving, the shift from first into second gear is often jerky, leading passengers to question your skill. As the driver, you can see your passengers' heads bobbing back and forth during every shift! Yes, in their minds, they are laughing at you.
This mod applies only to the following Zs with manual transmission:
Z3 2.5i, 3.0i (1999-2002)
Z4 2.5i, 3.0i, 3.0si (2003-2008)
I will confirm/cancel this during the week depending on weather I get the part or not.
Everyone is invited... And of course we'll have some Italian food on the menu. I'm thinking lasagne

When I get a chance to do the project we talked about, I'll let you and Bob know.
As a matter of fact, the only thing I will most likely never ask you to show me how to do is clean my car.
