Using DIY tester for boost leaks
I want to test my car for boost leaks and found out on here how to build a tester. I have a few questions though:
(1) Can you just pressurize the system from the MAF pipe without capping off anything else?
(2) Is it better to cap off the upper I/C pipe where it enters the throttle body. That seems to be 2-1/2". I'm not sure what I can cap it with. Home Depot PVC parts jump from 2.0 inches to 3.0 inches.
(3) In order to test the BOV, do you need to separately pump pressure into the line that usually goes to the intake manifold?
(4) Does the throttle blade stay closed for the test?
(5) How important is it for the engine to be at TDC? I see mixed answers on this one.
Thanks!
