Question about 1988 Honda Prelude
I have to disagree with diagnosis, sorry. Black smoke is rich mixture of fuel, & blue/white is oil and/or coolant .

It appears that there is an issue with the carbs on the earlier model preludes that can cause this problem. Like the old Fords with the Holley or FoMoCo carbs there is a power valve (or similar valve) on the Honda Carbs. If one of these valves goes bad the car will run rich all of the time and really rich (black smoke) when you first start the car. This was explained to me by a Honda Tech I know at a dealership. The valve may or may not be bad but may not be receiving vac from the hoses correctly. I have not repaired mine yet but I will investigate it further and report back.
