CDV (Clutch Delay Valve) Removal?

shaginwagon13 · 09-27-2012, 11:48 PM

Have about 70,000km on my car and I have been hearing a little bit of clutch chatter when starting in first and wanted to see how many of you have done a CDV (Clutch Delay Valve) Removal and who I could go to to get mine removed.....

Thanks!

Easy DIY. Remove the CDV and attach the hoses together if you own the vehicle or do the punch through method for a lease. lots of info on the site about this and it is a great little mod.

How did you go about bleeding the air out of the line after you did this??

Oldskool way of placing a piece of wood on the clutch pedal and opening the bleed valve, closing the valve, removing wood, replacing wood and repeat. Slow as hell by yourself, but tunes and beer make the job seem less tedious. Also, make sure your brake reservoir is open and full of fluid. Crimping the line before the CDv also reduces the amount of air getting into the line.

Did you find a link between the chatter and the CDV?

I ordered a modified CDV from Burger Motorsports and am waiting for it to com in. As soon as it does I am installing it for sure. When I am in Toronto traffic its so frustrating when my clutch engages at different points. I have been driving standard all my life and I feel like I still don't know the friction point with the OEM CDV.

My CDV came in this week.... Monday is a holiday in Canada for Thanksgiving so I am going to try and install it..... I'm a bit nervous about bleeding the line though, does anyone have first hand knowledge of how to best do it? I am going to be doing it with my buddy so I will have an extra set of hands for the bleed procedure.

kavadarci · 10-07-2012, 09:06 PM

i did it myself, no big deal. i have an x drive and had to remove the differential shaft to get to the bleeding bolt. pain but if you have no xi it's easy. again i noticed very little to no difference so hope works better for you.

How did you bleed/how do I bleed the line? Sorry for the 'noob' question but I have never done it before...
