Question about 1994 Isuzu Trooper
As a general rule, white smoke can mean coolant leaking into the combustion cylinder(s). Check your coolant level, see if it's still full, or if it's discolored (like oil is mixing into the water). Check the color of the oil, see if it looks like chocolate milk. If you're losing coolant, I'd say it's possible a head gasket, cracked/warped head, etc.
Make sure it really is white smoke -- if it's "blue smoke", it can simply be burning oil -- valve guides, piston rings. Or it was way overfilled with oil and the excess pressure is forcing the oil past the rings.
A compression test would be a good idea, as would a trip to a mechanic to check it out.
