ok so ive done a lot of research for a boost leak test and i got all the neccesary tools. I tried it on sat and fail(i was pressuring air in the turbo and couldnt get no air to go in the tire valve thingy)
ive noticed it is a bit different when you have an intake because you just take off the intake and plug the tester on the turbo

Difference to me is on my stock the stock air filter is stuck with the stock bov and intercool tubing all in one. SO i disconnected the hose that goes to the turbo but doesnt that mean everything else is disconnected?? how can i test out the bov if it has a leak.

ill put some pics because this sounds confusing since i dont know much part names hope someone can help

in this pic i see that all it takes is to unplug it and put the tester on, seems simple and the bov and other hoses are stuck to that intercooler piping thingy that goes to the throttle body

this is how mine looks. notice that the bov is connected with the air filer, intercooling piping etc. will it be different to boost leak test??

you need to remove your intake and attach the tester to the turbo. disconnect the bov from the intake and leave it connected to the upper intercooler pipe to avoid a leak.

This, and grab that breather tube from the Valve Cover that connects to your intake and pinch it while your pressurizing.

I don't like to plug the valve cover when testing. You can blow seals out by pressurizing the oil system/ motor.

Oh ok so I just disconnect intake, and the bottom part of bov but leave it attached to to the intake piping and that's it??

Do I have to cover the hole of the intake after removing it? Cus it'll just be dangling With a big open hole once removin from the turbo

No. You're removing the intake from the system, since it's not a concern during a boost leak test.

oh ok so the air intake has nothiing to do with test right?
that doesnt make sense though because in the stock intake the bov is connected to everything as well so it is ok to just leave the intake hose stuck on to the turbo just loose and open? sorry if im sounding confusing

removing the intake makes sense with the aftermarket one but the stock is connected with the intercooler piping and bov, where i might have a leak.

As long as you have a stable air supply, then the BOV should not vent/leak air until it reaches it's pressure capacity. If it does vent/leak, then you know that it needs fixed/replaced. It's all part of the boost leak test.
