UPDATE!!! 2006 Jeep 4.7l vacuum leak. What part is this?
Hey, my engine is making a wierd whistling sound, and I have narrowed it down to this thing. In order to fix it myself, which I know is cheaper, I need to know what this is. What is it?
Followed the vacuum hose with a friend, found out that when I bought it at Carmax, I had a piece of RED GARDEN HOSE
as a U joint for my brake vacuum line! I will post pictures under the appropriate post header later! I have to go to the store and buy a new piece and get it fixed tonight.
