Hissing vacuum sound and related codes... 850

posted by  someone claiming to be dpsc on  Wed Mar 31 06:01 CST 2004 [RELATED]

I'm dealing with a 3-1-5, 5-3-5 and a 2-3-2.....

I heard a hissing noise when the drivers door was open and knew it was a vacuum line/leak or similiar. I checked the three lines (blue, yellow and green) that go from the turbo housing to the air box. All plug into a relay or the turbo control valve at the bottom of the air box. My mechanic says that he's never seen one of these relays fail.

I see no cracks or breaks, but they are original, so maybe it's really not detectable to the human eye.

Has anyone out there had this problem?
