Just got done installing my modified CDV from Zeckhausen. Took me about an hour I'd say...most of that time was spent on getting a wrench on that bleed valve...it's tricky and there isn't much room to manuever. Actually replacing the CDV itself didn't take much time at all. I was shocked at just how much fluid came out when I uncoupled the old CDV before I could get the new on on. Now to go out and drive for a while and see what the difference is.
