Hello, I am sure people in the NoVA area has done the CDV mod but I was wondering if someone could help me with the mod or point me toward a shop that has done it for you. I have no idea when it comes to the bleeder. Thanks in advance.

Install is easy. Pop out the panel underneath the car, clamp line, remove clips, remove old CDV, install modified CDV. I have a modified one for sale in my thread if interested.

The install is really easy. It is the bleeding that can be a problem. It is very cramped in the bleeder screw location and very hard to accurately control the opening and closing of the bleeding screw. I ended up with a lot of air in my system and it took me quite a while to bleed it all out.

I would recommend using this method to bleed the brakes.

I was in the same position as you just this past Saturday when I installed my CDV. Install was easy but took me a while to bleed the clutch. It sucked b/c I had never done it before and I was calling around asking ppl what to do when I couldn't get good instructions by searching on the forums.

You need 2 people to do this! One person pumping the clutch from inside the car (your friend). And you will be underneath the car opening and closing the bleeder valve (use an 11mm wrench or 11mm socket / ratchet).

Have your friend pump the clutch 5-10 times then HOLD it down. While he is still holding it down, open up the bleeder valve (about 1 full turn). When it's opened, the air bubbles and brake / clutch fluid will spew out. Once it's out, tighten the bleeder valve. Make sure you don't over tighten it! Once the bleeder valve is closed, your friend can release the clutch. Repeat this about 3-4 times until you feel pressure in the clutch pedal again.

Can someone help me with this? I just want to make sure I did it right instead of assuming I did it right :P. I can compensate by means of food/beer/cash?

I feel like this is a lot of work haha. Do you remove the huge plastic under body protector on the front of the car?

I did install the clutch stop already. It was really simple and easy to install. Why can't all mods be like that? :P.
