Turbo or what 06 6.0

[maki1]

Dealership replaced turbo two weeks ago. The first week back it blew white smoke then heavy black smoke, no power, then as quick as it happened it cleared up. The turbo has a very high pitch wine to it. We were hauling a goose neck with a bobcat home tonight and it did it again, but this time we had to tow it home, Same thing happened, very little boost, and no power. We just did a pm on it everything was fine, we are having to add antifreeze at every pm,it was low tonight.

look at your overflow tank. Is there white residue around the cap? Not sure about the high pitch whine. Any DTCs?

remove ebps start the engine check if you have exhaust gas coming out of the tube look at the sensor see if it's plugged up

any mods? if you still have the egr cooler it could be causing the whisle noise and the loss of coolant. if the oil cooler it clogged or clogging the reduced coolant flow to the egr cooler could be causing the coolant to flash boil. the increased coolant pressure causes a tea kettle noise when it blows the steam out the degas bottle cap. If the egr cooler is leaking coolant into the intake manifold it can cause the white smoke your getting. park your truck on an incline front of truck pointed down, pull the egr valve (while its out make sure its not stuck open) this can cause power loss. look inside the intake and see if there is any coolant in the intake. if there is any coolant in the intake or it apears wet in any way DO NOT drive the truck till its fixed coolant in the cylinders will hydrolock the engine and pop your head gaskets. hope this helps

the heavy black smoke can be caused by the egr cooler, what happens is the residue builds up in your cooler so it wont let anything flow through creating a major power loss, i would get the egr checked out

coolant in the combustion chamber can(will) also contaminate injectors.
