I have no brakes due to vacuum pressure. I did a bbk tb swap and plenum swap. Thats all. I get some vacumm pressure in some lines the others have none. If i disconnect brake booster vacuum line (line that goes from rear of plenum to brake cylinder) and i blow into the plenum, i cant. I cant blow into the plenum at all (car off). If i keep trying to blow into it, it will slowly go in. When car is on, it suckes in very slowly. I know this is the problem why i dont have brakes. Could this be a plenum clog when the ported it??? calls will be taken 508-280-3793 kenny as i am very desperate and this is my daily driver. I will check on here too all day. I will be working on this car all day - yes all day christmas. please help. thanks

 

NEVERMIND. Plenum was clogged at the rear where brake vacuum line plugs in. dont ask me how but it was. thanks anyways

 

Wow. 20 minutes certainly beats the heck out of "all day". That IS a strange one though.
