So, how bad is this?
I noticed a round circle of soot on the ground under my tailpipe after starting it up. I don't ever see smoke out of it, although it's a few seconds before I can look at the tailpipe after I start up. And never see smoke while driving. Just noticed it today, and I see a second one from when I parked here two weeks ago (friend's house in CA). The circles are about 5" in diameter, clearly comes out of the tail pipe. The soot isn't wet.
Other fun stuff - my heater doesn't work??? Never had that before. Plenty of coolant, thermostat/cooling system working fine. The dash fan doesn't work, but still, the little bit of air coming out should still be hot, and mine isn't.
I read about a valve in the heater hose that can stick closed, but I didn't see one on this Eseries - it's prolly behind all the crap up front/top.
Also had smoke come off my Temla brake, which scared me, but it was just oil dripping on it. I'll find the leak when I get home next week.

No heat might be the blend door actuator. On the F-series, you can drop the glove-box and pull it off in about 2-minutes and see if it's actuating properly by cycling the hot/cold ****. They are plastic gears inside so they do break.
But I would get the blower working first...

Thanks, 5o. I think the actuator is working. When I turn the switch from Vent to Mix to Floor to Off, the air comes out of the different places. Gotta get the fan working for sure - it was cold in Flagstaff.

For the most part, I am unfamiliar with the E-series, but can you get access to the coolant return hose off of the heater core - just to do a "feel test" on it? It will be relatively cool to the touch if the heater coolant valve is there and closed.

Thx, Mark.I'm going to find that valve/hose when I get home. It almost seems like it has to be that valve. I'll be in warm climes after today.
How about that soot, is that normal or maybe it means my turbo is filthy?

Not real sure on the soot,but I guess I would first make sure all the air flow components are in good shape (good air filter, no charge-air leaks, etc). You might also verify that IAT1 and IAT2 are reading ambient temperature after a good "cold soak".

OK, I'll program those gauges to monitor. I never see any smoke, just the circle appears on the concrete. Today, it looked a bit shiny, like liquid, but nothing on my finger when I wiped. I'm not sure if it does it as soon as it starts for a few seconds, or is always doing it. I need to monitor it more closely. These buses typically have so many idle hours that I expect them to have dirty turbos. Prolly stupid, but I had the idea that my driving style - hour after hour, hundreds of miles, at highway speeds - might kinda "self-clean" it.
