Hose melted on exhaust

[Haymaker]

New to YJ ownership, new to working on my own vehicles, please help. Just bought 95 Wrangler 2.4L 4cyl with serious oil leak, just got it back from shop after 7 weeks. Noticed tubing underneath had melted, tracked it to inside engine compartment. Please help identifying and fixing.

Is the Jeep running still? Are there any wires inside the loom in the bottom picture?

Jeeps still runs. There are two rubber hoses inside. Feel ignorant, but really want to learn.

That's the vacuum hose system that operates the front axle disconnect. It's supposed to start at the intake manifold, go across the firewall over to the battery where it heads down and splits to the transfer case and front axle.

Your previous owner deleted that system and put on that cable front axle actuator and left the hoses dangling. You can remove all that tubing all the way back to the engine and then just cap the port at the engine.

I got rid of that system long ago, though I did not replace with a cable setup like your PO did. I got rid of the front axle disconnect entirely.

Thanks a lot. My mechanic reconnected the power to the disconnect which cause the 4WD indicator to come on. My initial plan was to remove all the hoses but I wanted to make sure I wasn’t removing something I really need.
