Re: What would cause every cylinder to be low on compression?
Sounds like a head gasket.. I mean they pointed out coolant in the cylinders and all cylinders are low and you have white smoke. While white smoke is usually assoc with injectors and raw fuel, it's also a symptom of a blown head gasket. If you have Diesel in your coolant overflow reservoir then it is an injector cup or two. But unlikely a cup due to your other symptoms.
I love the "ya dusted yer engine" WTF, the fact you have coolant in the cylinder is an automatic fix it before a compression test. Was that a Ford dealer?
