I have a 2000 Discovery II and was replacing the cat converter and O2 sensors over the weekend, and while I had the D2 on the jack stands I noticed 3 plastic lines/tubes that were broken and sealed due to heat. The 3 lines are running along the passenger side of the engine (currently attached: running from the rear to front, where the front no longer attached to anything), next to the oil pan and exhaustmanifold, and all 3 were severed in approximately the same place (within 1/2" of each other). They looked to be severed due to a a break, and as a result of being near the exhaust/cat a couple are melted at the end. Below is a photo looking down from the passenger side.


I've searched the RAVE manual and cannot figure out what these lines do, nor can I find a place where they should be attached. I have brakes, and am having no coolant leaks, so my guess is they have something to do with vacuum and perhaps the emissions/exhaust system.

Anyone know what these lines are for? Thanks.

 

Are they the breather fuel hoses?

I found the same thing on mine. Hoping you figured it out?

 

Breather tubes, This question is asked over and over again on here.

 

those are the breather tubes for the transmission and/or the front differential.

make sure they are open and not melted shut.

if you do any off-roading and, specifically, wading you need to replace the breather hoses and get them up higher so water will not get into either the transmission or differential.
