1G Boost leak at maf

[dsmBear]

I did a blt, and found 2 leaks at intercooler couplers, I fixed them, did the blt again and leaks gone. Next day I start up and drive but it still feels like a massive leak. Me being lazy and not wanting to remove the intake and my catch can and small coolant bottle, I made a mini tester that clamps onto the bov reciric tube, and low and behold I hear and see bubbles coming from the maf (1g oe maf) I couldn't find anything about the mafs leaking, should I just find another one and throw it on there

Huh? Where's it leaking from? It should be at either end of the MAF where the coupler goes into the intake or where the air filter bolts up to the MAF.

Sounds like from where the air filter is, but I can't feel it or see it, I do have an extra filter I can throw om and try

Lol are you sure it's not just your air filter breathing like it's supposed to?

Well I have a bad boost leak like I can hear it and feel it. I have no other leaks if I hook up the coupler directly to turbo

Wha?? If you're blowing air down the recirc tube, of course its going to blow back out through the maf and air filter. Its a giant open hole. Does the gauge on your tester hold at 0psi?

yeah well my boost gauge does, and ok yeah that makes sense feel kind of stupid now but yeah my boost gauge holds at whatever psi i out it in, but when driving, espeically when cold you can feel and hear the boost leak

Sorry i didnt mean it that way, i was just a bit confused as to what you were doing.

The maf wont seal though, its a giant open hole with a screen on one side. Pulling the intake pipe off is a pain but you have to. If you can hear it while driving then its either a really big leak or the line to your boost gauge is leaking.
