I drive around and every once in awhile when I decide to actually go WOT and shift fast I can't tell if my clutch is actually slipping or its the CDV. Sometimes the delay is noticeably much longer, and other times i'll get a nice chirp into 2.

Any insight?

thanks,
Josh

 

98% sure CDV.

How many miles on your car?

The CDV valve is fairly easy to replace.

 

I'm at about 20,500...the delay/slippage seems to be longest on the 2-3 shift

 

Well either way, the CDV is far easier and cheaper to replace. I would do that first (even if your clutch is fried, you probably will want the older style CDV anyway.) Then check it out, if it still slips, get a new clutch.

Unless you are a terrible driver, and beat the CRAP out of your clutch it should last much, MUCH longer than 20k mi.

 

what does CDV stand for?

 

CDV = clutch delay valve

and im willing to put money on it being the cause - I had the same thing at ~10k miles.

removed the cdv and not had it since

 

Don't worry, Greg. It's a 2004+ thing. You don't have a delay valve.

 

If you drive hard, (hard launches) the CDV will save your diff and clutch over the long haul. But I agree it really kills the that crisp shift feeling.

 

How difficult is the process of removing it....for someone who hasn't really ever done work on an engine before?

 

Well, your question kinda scares me. It's not anywhere near the engine.

Actually, it's pretty easy. I'd be happy to help you with it (I've done one already.) Unfortunatly it's a bit of a hike for you being in WI.

S2000GT had some write-ups we used when we swapped over the '03 slave cylinder and removed his '04 slave. We followed those, and it went ALMOST smoothly. When we put the new one on, it did not engage the fork correctly. So it did not acuate the clutch. It's a fairly common mistake when installing a slave cylinder. Fortunatly, we noticed it before we put the car back down so it was easy to get back in there and fix it.
