I was looking over my engine today and I noticed while checking the spark plugs that there was a piece of tubing in the back that wasn't connected. Lo and behold it's the tube that connects to the *front? side closest to seats* valve cover. I followed the tube and the other side wasn't connected either... Is this supposed to be a tube where filtered air gets into the valve covers? The guy removed the airbox, put in the filter with a towel over the end and left this tube unhooked... Is my assumption right?

Is this a metal tube? The only tube that I can think of that goes into the front valve cover is a metal tube that goes into the air tube just past the throttle body. Is that the one you are talking about?

------------------

Im assuming your talking about the tube on the 2.8 V6. That tube was a short piece of rubber that connected the valve cover to a metal tube that then ran across the firewall and then connected to the airbox with another small rubber tube. That whole assembly fed fresh air to the valve cover. That tube was disconnected and discared during one of recalls so no need to worry.

I don't know which one is front and which is rear, if someone could specify that would be great, but what this tube does is run from the valve cover nearest the seats, farthest from the trunk, there is a 90 degree elbow, then some rubber tubing that runs to firewall then back out towards airfilter / intake. Neither ends are attached though so I don't know where it's supposed to go

Is this tube closeset to the passanger or drivers side?? Theres actually two tubes back there..the one on the passenger side was the one that was taken off during the recall. The one on the drivers side should still be present and there should be a rubber grommet in the valve cover that connects to a black metal tube that then connects to the rubber intake tube right before the Holley throttle body.

Close to the throttle body, on the big rubber hose that goes to the air cleaner, feel the back side of the hose and you'll find a tube sticking out with a hole in it. If you find the hole and no tube is plugged into it you have your answer.

So what would this do to a running engine. The air filter is not in a box just out with a towel over the end, and this hose has been disconnected for a while i guess letting unfiltered air in as it pleases.

Well it depends on a couple things..number one what hose it exactly is.. and number two how exactly the air filter is hooked up..got any pics??

soud like its the hose that orginally went from the back valve cover to the air cleaner housing. This was to vent crank case pressure. I believe it was recalled because with oil fumes and such pointing right at the filter, the filter got dirty and moinst real fast. This was recalled and a new tube that goes from the back valve cover to the rubber air intake hose from the cleaner housing to the throttle body was installed
