Pcv ?

[RS6 rick]

Hello.......Thought the PCV lines coming off the valve covers was a direct vacuum source. Was going to use it to due some CC cleaning but no vacuum.What am I missing ? Thanks for any and all help. Be safe.

Valve covers won't have vacuum present. You'll need to tap something in between the throttle body and intake valves. I believe there are some vacuum sources under the air box.

BTW, what is CC cleaning?

Thanks for the quick response. CC stands for combustion chamber. Be safe.
