Chevy Silverado 1500 7.5L thick white smoke pouring from exhaust

[Patemichael78]

Idols high with loud whining. Bogs out on idol. There is NO water in oil. Replaced distribut, rotary button, ignition control module and fuel pressure sensor less than 1 week ago. Im going crazy here...one serious issue after another!!! Please some advice here. ..

white smoke is an indication of antifreeze getting into the exhaust, blown head gasket, cracked head, intake manifold gasket, etc. Have you noticed a loss of coolant when checking the level on a cold engine? Have you done a hydrocarbon test on the engine coolant? Have you pressure tested the cooling system?
