Hose from engine block venting exhaust underneath bus?

[Elliot Naess]

Don't know, but I'm thinking Road Draft Tube, for crankcase ventilation. In which case that "exhaust" might be excessive piston-ring blowby.

More importantly, I think you have just seen a good example of why you should buy a bus directly from a school district, and not from "one of us" who has bungled the thing to death.

crankcase ventilation

+1. That's what it is.

The fact that those (oil?) filters have been installed long enough to get that rusty would be enough for me to walk away from it.

You're right EG, those are rusty oil filters. That takes years of neglect to get to that point. My M1009 daily driver was parked in a government field for three years without any care and the filters did not look that bad...
