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.

+1. That's what it is.

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...
