The picture of the slobber tube mess on the concrete floor looks like some green liquid in the third frame. Are you running green or red coolant?

It’s red.

I feel like I need some education about this tube. I’m assuming it’s a vent tube for the valve cover. As it’s referred to as the “slobber tube”, is this tube also known as a crankcase ventalation tube?

[Richard]

Yes yes yes. All tye same thing, and it normally does not produce a steady stream of vapor. Collect that vapor to see what it is. Water, coolant, exhaust, or oil. Something is amiss.

If it was my coach
For peace of mind, I would pull a oil sample, send to lab, make sure coolant was not in
Oil. If report comes back OK, I would drive it

Talk to a shop that does a lot of DD60 work. Might be something simple in the crankcase ventilation system. If possible show them the video & pics. As well as filling them in on recent repair work that has been done.

[jdkskyking]

I’ll pull a oil sample and start there. 

Thanks for the advice, I’ll keep everyone posted.

If you decide to drive coach
Think about placing a hose on the vent tube.
Get it down to about 1 1/2 inches off ground
That will keep drips below engine

How about a catch can set up. Plastic bottle so I can see what comes out of it.

Good idea. It's been done by truckers on engines that have a lot of blow by to keep from making a mess. They were called "puke bottles". Be sure that you have plenty of ventilation on the container.
