That could be coolant burning off at startup. Possibly a head gasket leaking on the intake side. I think that's the only way coolant can get into the cylinders other than a cracked block, but it would be overheating and losing a lot of coolant if that was the case.
If its oil burning off........it would be leaving deposits on the tips. Take a look and see if there is any oil on them. If it's oil, then it's getting past your piston rings.
