The indicators you have described are consistamt with a head gasket leak. The coolant is able to get into the cylinder on a one way trip that is seeping through a tiny pinhole or flat surface leak. The rate is so slow that the combustion pressure, and compression have little time to force there way into the water jacket. Byt while shut off, the coolant pressure, and time combine to let a thimble full of coolant into the cylinder. This causes the white exhaust till it burns off, and then the engine runs pretty well. That coolant loss is not a miricle dissapearance, it is real. Smelling the white exhaust can also be an indicator. Coolant smells sweet and destinctive. If you pulled the injectors out, put a pressure tester on the radiator and pumped it up to the cap pressure rating, and waited 24 hours, the cylinder with a leak would spit coolant out the injector hole when first cranked. Best of luck, Jim

When dealing with thinner metals like sheet tin, a long bolt and
