Here's the tubing assembly in my car:


Here's what Nat Brown posted just recently:


I think we have a small discrepancy here. :)

Finally we can put this all to bed.

Remove that bugger and let us know how it goes...make sure you bleed your clutch hydraulic system afterwards though.

That's definitely the next step... Are there any good ways to bleed the system with only one person available? (I can get more, but most of the people I know are squeamish types.)

Powerbleeders/Vacuum bleeders work well. Just hook it up to your brake hydraulics, fill up with a quart/liter of DOT 4 brake fluid, tighten the lid and pump until ~26-30 psi. Hook up clear hose to clutch slave cylinder bleeder valve, open valve and wait until no air bubble comes out.

Or have a friend keep pumping the clutch pedal until no air bubble comes out.

Sorry for the question, but...

What does a Clutch Delay Valve do?

It literally slows engagement of the clutch. It takes away driver control and increases clutch wear.
I'm going to excise mine tomorrow. :)

So if it's an overly bad thing -- why is it there in the first place?

Honestly, no one has come up with a good reason...
Some say it's to protect the drivetrain...
Some say it's to help newbie drivers.

:dunno:

I am really curious to hear how much of a difference it makes. Good luck being the guinea pig :thumb:

If you haven't already, take a look at the CDV removal tips on bmwtips.org. Looks like some useful info in there.

Grr.

I'll post pictures when I put the car back up on ramps to re-install the CDV after I drill it out. The truth is, though, that aside from the forward driveshaft, it looks EXACTLY like yours and Nat Brown's now that I've taken the damned thing out. The part I removed looks exactly like what UUC posted, although the internals seem a little bit different.

I'll take pictures of it tomorrow.

Nick, that's damn good news.
(Nice to be wrong, and happy about it!)

Let me see if I have the nuts in the right sequence and function, from left to right in your picture:

- Flare nut that holds the end of the metal tube.
- CDV nut. (looks like one, with a smallish one attached)
- Nut for end of rubber hose.

Removal is as you said, loosen flare nut, remove hose with CDV attached, remove CDV from hose, stick hose end into bracket and Tighten Flare nut into hose.

My rough shot at a photoshop guess of how it looks removed is below:



Right or wrong?

Exactly correct. :)

When I drill out the CDV and re-install it, I'll provide proper pictures.
