White smoke: antifreeze burning. Head-off time. Blown gasket or head
crack to waterpassage.

Blue smoke: rings at least. Indicates worn/softened oil rings or
cracked head penetrating oilway.

Black smoke: injectors need cleaning, adjusting or replacing and/or
fuelpump pushing too much fuel and/or pump timing out.

Warning: a diesel (or gas engine!) pumping too much fuel can suffer
from excessive cylinder wear due to washdown of lubricating oil by
the excess fuel.

That's A 3.0 five?
