I would really like to do this and not have to drill anything! I am hoping this cdv delete might help prevent clutch slipping. Also, has anyone successfully removed these parts in the slave without removing the slave from the car?

Without the spacers and stuff the line was dripping, and leaked a lot more when clutch was depressed.

I even tried vacuum bleeding with a hand held vacuum pump. I needed the syringe to purge the bubbles upwards.

then you need to bleed the line and get the air out of the high spots. I was able to do this with gravity bleed. magic or whatever, I did it. I know it's given others a hell of a time. in the end, just get all of the air out. |

I thought I’d follow up on this. After modifying the restrictor I decided that there was still too much material restricting flow in the line. So I went back in and removed the restrictor and rubber bushing. I got even better clutch feel and unlike someone else posted, there is no leakage from the connection of the hard line to the slave.
Lots of you have complained about bleeding the line afterwards. I think you’re not giving the pedal enough time. I’ve done this twice now. I reverse bled the first time and pressure bled from above the second and each time I got significant air coming out. I continued bleeding until there were absolutely no bubbles. Each time the pedal was soft but repeated pumping improved it and driving finished it off. |

But my slave was leaking like a mofo when I reinstalled the line. I had to dig my plastic/rubber spacers out of the trash and reinstalled those to keep it from leaking. My only guess is that the line rest against the rubber piece forming a seal when inserted. This is just my experience. Im still curious as to why others dont leak? I would want more clutch control if possible.

You probably had the nipple pop off the connector to the hard line.
It seals fine without either piece for the CDV, as long as the rubber nipple is FULLY on the hard line connector. It goes partially on with a slight click and then fully on with a loud hard click. |

This is something I would be interested in, but definitely not knowledgable enough to do it myself. Any shops in the LA area that anyone recommends to tackle this?

Exactly! Or even a forum member who has done a few of these could buy a bunch of clutch slaves, do the mod, and sell on here for a profit. And when they ship it out have some proper step by step instructions to do the install from start to finish along with proper clutch bleed method... because this entire thread has multiple ways to do the mod, and even more ways to do the bleed and not very many pictures.

I finally tackled this today. I got to say, it was easier than I thought.
As far as modifying the slave cylinder, there's absolutely no reason to drill. You can use a pick or anything pointy to remove the rubber bushing. To remove the metal restrictor I found pushing the valve of the slave cylinder in pushes the fluid out against the restrictor, which dislodges it and makes it easier to pull out. Installation was a little more difficult then removal, mainly getting the top bolt started. I tightened the lower bolt first to fully seat the slave cylinder, but not all the way. You need some play in it to get the top bolt in. The top bolt took some patience but I finally got it started and tightened it down. I then pushed 200mL of fluid through the valve and that seemed push all the air out. |

Im pretty sure he means through the slave. For some reason normal older bmw slave bleeding procedures didn't work on my F30. Had to do the syringe method as well.
