I am trying to reassemble a 2010 Legacy GT 2.5 turbo hose system.\nMaybe someone who has one can maybe look at their car and answer these questions.\n\nWhat is the device that is connected, like an appendix, on the pressure side of the turbo and what is its function? It has a short larger diameter hose connection going downward that connects to the low pressure incoming air duct. There is a connection on the top left of this device that has a slip on nipple for a small diameter hose.\n\nWhere does that small hose from this device go to when it gets near the top side of the engine?\n\nOn the turbo there is a small hose that comes off of what appears to be an oil catch pan on the bottom of the turbo. Where does that hose connect when getting to the top of the engine?\n\nAnd what exactly is that pan on the very bottom of the turbo?\n\nThanks to everyone who reads this and can help answer my questions. I am an old guy (75) and am finishing the build of a car using the Legacy GT 2.5 turbo in midship location.
