Broken hose? Help!

[EpicRex]

Hello everyone,

Can someone help me figure out what this is and give me an idea on repair/replacement costs? I attached pictures because I don't know how to explain what I am looking at. The hose is located near the base of my air intake. Somehow the hose snapped off. I am certain this happened when I last took it to my mechanic. When I confronted him about the hose, he pretty much blamed me which is BS cause I would have known... anyways - that's a whole other deck of cards...

From what I can tell, the piece is plastic but I can't see how far it goes down or what else it is connected to because the motor is in the way. I've circled the problem in RED. Let me know if I can provide any other clarification and I will do my best. Pics below and thanks ahead of time.

If I recall correctly. That hose is connected to your boost solenoid.
I'd not drive it or just not go into boost until it's fixed.

Best remedy is a new turbo inlet hose. Have fun.

Do you have boost leaks? Maybe you can buy just that section of pipe that might come with that piece of plastic, and all you have to do is plug the hose in again. Maybe cost around 100 bucks from subaru parts because dealers parts are ridiculously expensive

Hes not gonna have a boost leak, hes gonna have a massive post maf vacuum leak which could potentially blow his engine. Replace that inlet ASAP.

That plastic part thats supposed to go on the inlet is part of the mold. Sadly it can't simply be replaced... glued on maybe... but is that really a smart route?

Seems like an easy enough fix. Get a new inlet, and don't drive until then

Yep that's the boost control vacuum line. The vacuum helps to draw out the pressure in the bleed off boost control system. Without this line connected you'll have a hard time making boost with your current WGDC and TD settings.

Don't be dramatic. The MAF will rescale LTFT via closed-loop fueling. Not that the OP shouldn't replace the inlet as vacuum leaks can contribute to non-linear MAF registration, but this issue puts the engine in very little danger of "blowing up."

I'd still worry like a mofo. LTFT should help under low load but when my after maf had a minor crack(tried sealing it up) it would max out my STFT and caused plenty of knock under boost =(

STFT are not applied under Open Loop fueling conditions.

Thank you for correcting me, Zax. because I just broke my bittle-ass vacuum lines! The whole damn thing is solid.
