Boost Leak testing question
Hi Guys- I want to do a thorough leak test. I'm gonna do it from the intake of the turbo like the vfaq. I don't understand it though. Won't the air that i'm pumping in just leak out the exhaust valves? I've read some posts that say to set #1 at TDC but i don't see what good that does because setting it at TDC doesn't close all the valves. Some are open some are closed. Can someone please explain to me how to boost leak test the entire system. I could block the 2.5" pipe before the t.b. elbow but i want to test the whole system. The vfaq doesn't explain this.
Thanks.
