I'm not sure what it is called, but it looks like $$$ to me. ( like the upper rad hose or Crankcase breather hose) I did seal off a leak in the michelin man hose a few years back by cleaning it thorougly and then wrapping it in black electrical tape followed by duct tape. It held boost fine until the new hose came and I still carry it as a spare.

Hey all,

Finally located a boost leak that's been haunting me for a few's the hose between the intake tube and the ISV and the throttle body, at the rear top of the motor.  It's about 2-3 inches long, and has three holes......two larger diameter between the intake and the throttle body, and one smaller that leads to the ISV.  Any part #'s, proper name, sources, $'s, and such would be much appreciated.  It's probably called something simple, like the "throttle body hose" and is dealer only for many $'s, but I'm drawing a blank at the moment.  Thanks!

BTW, anyone ever had any luck with sealing an intake hose leak with some rubber bonding adhesive, like a Shoo Goo or Rubber Raft glue, even for a temporary fix?  I'm tempted, especially if it's a high dollar dealer only part, but don't want to screw anything up.  Any BTDT, or reasons why I shouldn't try it on this one?  

Thank in advance....
