My truck lost power and started blowing white.

WHITE - WHITE?LIKE STEAM? CATCH SOME OF IT IN A BIG CLEAR ZIP-LOCK BAG OR EVEN HOLD A JAR CLOSE TO THE PIPE

NORMAL COMBUSTION WILL CREATE WATER MIST. BUT VERY LITTLE (TRY IT ON A NORMAL RUNNING CAR) IF YOU FOG UP THE GLASS INSTANTLY. YOU MAY HAVE A HEAD/ HEAD GASKET ISSUE

HAS IT RECENTLY OVERHEATED? (A BLOWN HEAD GASKET DOES NOT NECESSARILY MEAN OVERHEATING CAUSED IT)

OR WHITE/ BLUE/ GRAYISH? ---LIKE OIL BURNING?

IS THIS DOING IT ALL THE TIME?

HAVE YOU CHECKED OIL AND WATER LEVELS? ARE THEY NORMAL?

DO YOU SEE ANY SIGNS THAT YOUR OIL HAS WATER IN ITWATER HAS OIL IN IT?
