And tell me where it goes? I just "found" it while doing the intake gasket replacement and can't seem to find where it goes, and now I have coolant leaking.

 

looks to me like it is the tube that goes from the pass. side valve cover to the side of the throttle body. of course that wouldn't describe the leaking coolant.

 

I agree. It fits into the hole on top of the passenger valve cover. Has nothing to do with a coolant leak.

 

Well that makes sense going from the valve cover to the TB since that's what I was messing with. I did the TB bypass when I was messing with it so an unused nipple got overlooked. So I have a coolant problem, Yay!

Thanks for your help guys.
