Ok, so I got the valve out but it was difficult because of the tight spacing. I will test before turning it on, but I'm getting ready at the air filter area first. Do I remove the entire metal housing of the air filter, bowl and all? If so, how do I get that big hose that connects with the turbo to let go of the housing? I've loosened the hose clamp but

it won't come off. Can I dismount the little dangly thing that goes down in side instead, and cover that hole?
Sorry, this typed 1 handed and a little strange.
