Cdv removal

I'm sure you *could* get away without bleeding it... but I wouldn't (and didn't) risk it. Especially when brake fluid needs replacing anyway.

I think the CDV-delete hoses are better (they are braided for a start) but I doubt they make any actual performance difference.
 
Even though you clamp the pipe some fluid leaks after the clamp which is replaced by air. It’s a bit fiddly in access terms but so easy to bleed it’s not worth not doing it imo. I bled mine, IIRC 8mm small ratchet spanner is the easiest. :thumbsup:
 
I'll be doing a full fluid change before too long so I'll bleed the clutch as part of that. I drove for an hour after removing the CDV and didn't have a problem. The decision not to bleed it was more out of interest than anything, following what people on here had said :D

Where are all the forum members who delete CDVs in 5 mins by clamping the hose without bleeding the clutch and never had an issue? This was the de-facto method IIRC, I'm sure I didn't imagine it :? :D

Bleeding the clutch: 30 sec. job (literally have the second person push and hold the pedal, and opening/closing a screw)
Replacing a clutch that has worn out too soon: 5 hours job...

If you had done this job yourself you would have noticed that its impossible to open up the system without any leakage.
When you clamp off the hose, thats impossible to do at the very end, and the hard line on the other side also looses a drop or too.
Every drop you loose is replaced by air in this case, and the slave cylinder isnt self-bleeding (only the master cylinder is I think....)
