The hose was fairly well covered in oil and when I had the IC out, the hose felt really loose, I could turn it easily.

Iv researched this problem but haven't come across anyone saying a symptom being this kind of noise but I would imagine there would be some kind of noise coming from there is the hose is that loose.

Anyone have any thoughts on this? BTW I already ordered the Forge hose.
I replaced the boost hose with the Forge piece but same noise is present so the car has been dropped off at the dealer.

Will update again after I hear back from the dealer.
