Picked up my car from the shop. Got into my car and notice my brakes were acting different. It feels like my brakes pretty much hit the floor. After a while driving the brakes got better. I got on the car like 2 times on the highway and notice my bov wasn't working. The shop took the motor out and reinstalled the motor and install my catchment. The catch-can was run from the valve cover. When i get on my car the car reads 19-21 vacuum and when i step on it the needle goes to 13 but it like shakes like its trying pass 13psi and my bov doesn't work. i check to make sure i had vacuum 2 my bov and there vacuum there. is there anything else i should be check? Was i suppose to block off the stock catch can in the back of the block? my bov was working prefect before i drop it off. thanks

 

So I'm guessing you didn't actually install the turbo setup yourself. Did you check the vacuum source to your BOV? NEVER take your car anywhere that doesn't know about boosted cars.

 

Definitely a vacuum leak. x2 taking your car that know nothing about boosted set ups, they never get **** right. Off topic, @grumblemarc, that's cool you live in Oak Ridge, I'm building a D16Y8 turbo set up for my Del Sol, then I'm of to.... THE DRAGON!!!

 

i have a feeling you have something tee'd in after the check valve in the line for the brake booster.

 

Did the Dragon last year for the first time just before it got cold. It's no joke. Don't let your ego drive the car or you could find yourself going over the side of a drop off.
