Another failed boost leak test...

[jwahl16]

Ok so I don't want to sound like a noob but apparently I am since I can't get this right. I decided to take another crack at a boost leak test today and couldn't build any pressure. I blocked off my mbc, and my crank case recirculation tube (that had some air coming out) but i still couldn't build any pressure. It sounded like air was leaking down by the tester or the turbo. Is it possible for the turbo to leak air without leaking oil? I bought it used last year from a very reputable member on here so i believe it should be fine. There is no shaft play or anything. How should i go about testing my tester? Buy another pvc end cap and plug up the other side and pressure test it? I also think i'm going to try testing from my upper intercooler pipe next time to try and elliminate those leaks first. This is just frustrating, I can replace turbos and other parts but I can't do a simple boost leak test. And it's already dark out so I'll have to try again tomorrow.

First question would be how are you testing it.

use a squirt bottle with a bit of soap and top it off with water. if it won't hold any psi there's def a leak. and check the intercooler for cracks too. and yes a turbo can leak around the compressor cover seal . but it usually isn't that much.

im using a air pump that lugs in to my cig lighter. yeah goood idea, ill pic up a squirt bottle tomorrow when i go to buy some better clamps. yeah i figure i have a leak, its just been a pain to track down.

Best way to to do is with an air compressor because that little pump doesn't push out enough air fast enough. But obviously you have a decent leak somewhere.

Find a real air compressor, I've tried the same thing before it does not work.

ok thanks, i'll also find a real compressor as well
