Ralph, usually (not always, but usually), Blue smoke = engine oil burning; White smoke = power steering or coolant, Black smoke = rich gas mixture. So yours falls under the power steering fluid or head gasket. Since you are also losing PS fluid, that would be the logical guess.

I am not super familiar with the ES300 power steering system but I understand that there may be tube from the steering system routed into the intake plenum (for vacuum) to make the power steering more sensitive at lower RPM (for ease in steering out of parking spaces). It may be that a valve is leaking and allowing power steering fluid to be sucked into your intake plenum. Read the following thread carefully and decide if this fits your symptoms. It may give you some ideas of where to head next -> http://us.lexusowner...showtopic=51234
