Default boost leak general area advice

hooked up the pressure tester and heard a leak coming from behind the engine, passenger side, pretty low. i had my soapy mister and still couldnt locate the leak. i only had about 3 minutes worth of testing because my compressor stinks.

any advice on what specifically to look at in that area that is a common leak source?

Default what are your mods please?

also, did you go under the car? when i think a leak is coming from back down there, i can usually find it by going underneath the car. check the hoses coming right off the pass side turbo.. get a flashlight and lay under the car

Default thanks, that was going to be the next step

but given my limited amount of compressed air didnt lift it up yet

hoses from passenger turbo, added to list.

i just got k04s put on and want to make sure there are no leaks before starting to adjust my fueling.

Default when i had my AWE kit installed...

i had leaks at all of the injectors (was a BYTCH to find, couldnt figure out where the air was coming from), and one of the hoses on my pass side turbo was hanging off. turns out the injectors were leaking because the mechanic installed the clips and he wasnt supposed to. follow the piping off the pass side turbo as far as yuou can see. good luck!

Default K valve and the vac hoses there..

or the N75 vac hoses ..
keep the system pressurized and move/touch the hoses .. the sound will change when you find it .. PLUS that piggie MBC is crap .. it doesn't seal right , so i think that might be it .. i played with it a bit and it was not holding perfectly pressure .. and i was using my mounth .. cheap **** .. ;(
