[QUOTE="Dajain, post: 133329, member: 24595"] I worked in the underground mining industry for years and an intake shut off is required on all heavy equipment for underground. Wouldn't be a bad standard to adapt to all diesels, but I'm not the engineer designing these things. lol The guy that told me it was white smoke really isn't any kind of diesel person. He said it was white smoke but I could smell that it was burning oil. And sorry, but I have to correct ya on this one. Unburnt fuel would be black smoke. In the truck world, they call it rolling coal. Coolant (Which the bobcat doesn't use) would be white. A bad injector, or a cylinder lean condition could cause white smoke also. Burning oil would be light blue and could be considered "white" to the untrained eye. The other source of black smoke is if the engine is on fire and everything rubber on it is burning. But, the knock should be a fuel knock, like you said. With the turbo not spooling up, it's dumping the fuel in but not getting the air delivery needed. During restart, it acts "Flooded" but restarts and clears the cylinders out. The motor is a [B]Deutz BF4M 1011 engine[/B] [/QUOTE]
