M35A2 Hose Hanging On Side Of Axle

[Hummer Guy]

Anyone knows what this hose is and where its actually suppose to go? I assume its a hose for a CDR valve that's missing but I don't know

It is the crankcase pressure relief. Normally when running you will see some steam coming out of there. Black slime too.
If the engine has a lot of blowby you will see more.
Technical term is slobber tube.
