You guys have at it I would not touch this one with a pair of rubber gloves good luck
well, another detail I left out was that I was driving along in Montana and all of the sudden I got a surge of power and the bus ramped up to 75 mph and rocketed up the hill in 4th
Sudden surge of power rocketing up the hill- tells me your engine is burning enough oil to be running on the oil (like having bigger injectors). Be aware that sometime you might have a run away engine with it running on the oil. Make sure your emergency shut down flap is working correctly. Sounds like you'll be needing it soon.
