I've probably reached my quota of questions in the last couple days, but I have another. I let my bus idle for about 15 minutes this evening then pulled out on the highway. When I took off, I got a terrible cloud of white smoke (obviously oil). It lasted for just a few seconds, but was really embarrassisng. I looked like a truck killing mosquitos.

It acted like a bad case of leaking valve seals, but that is normally most obvious when you turn off the motor then start it a few minutes later, allowing the oil to drip past the valve seals into the bottom of the head, then blowing it out when you start the engine.

Any suggestions as to what may have caused the smoke? I don't really know anything about the 8V92. Does it burn more oil than a 4 cycle diesel?
