I cleaned my EGR orifice today, and while I was following Bay13's excellent resource for this I came up with a few questions. The large hose that connects to the throttle body has another smaller hose that tees into it from - I think the idle air pump. On Bay13's page the large hose has been removed and the smaller hose is hanging in mid air. I tried hard to pull the smaller hose's end out so I could get the large one out of the picture, but they seemed to be one and the same (glued?). Bay13's hose is nice and clean and appears to have come off a fitting, while mine protrudes into the large hose and is covered with oil gunk. Just curious if anyone knows if that smaller hose pulls out. My second question is about the clamps that are on some of the aprroximately 1" hoses around the idle air pump. They don't appear to be reusable, and there aren't any screws. There is what appears to be a deep crimp in them, and three teeth that engage slots. Sure looks like a special tool installed them. I am asking because I wanted to remove one of these hoses to make my life easier. My third and last question is about overall airflow on the 850 turbo. It appears air leaves the air cleaner and heads towards the back of the engine, near the exhaust. The large hose to the TB does not come from the air cleaner but rather connects to the shroud above the radiator. I am an idiot because I expected the air cleaner to feed air into the throttle body. Can someone explain the basics or point me to where I can find them? As always, thanks for any advice. Don 854T
