1st place to start is the turbo oil leaks. Maybe the turbo is leaking oil into the engine too. But, ususally white smoke is a fuel problem.

Was the truck running OK with the hybrids and chip or is this something that happened after they were installed?

I would vote the turbo has puked. 530's would be enough to build more boost than the turbo can handle. white smoke can also be antifreeze burning. head gasket or cavitated cylinder. any check engine light? like cuda asked was the truck running good after the mods were installed then this started?

That sound you heard was likely the wind pump saying "Bye Bye". I followed a Dart truck across two states blowing white & smelling like a bug smoker after he puked something in the turbo.

You say "taking it down the track"......as in racing? If you were pushing it hard and heard 'something', I agree, the turbo took a dump or what ever was causing the white smoke b4 taking down the track.

Was the knocking when the truck was running or jsut when you has the turbo off the truck you flipped the turbo over and it was knocking? Or you put the starter back on and started the truck and it was knocking? Also the turbo should have nearly zero side to side movement. As in not be able to feel it with your bare hands

my vote goes to the turbo. especially since you got oil coming out the exhaust. if you had no oil i would be thinking a head gasket but you sound fine.
better start shopping for another lung for that beast.

i would concentrate on that and making sure that is right then fire it up. if you still have problems then look other places.


fwiw most of the time when a head gasket goes on a stroke it starts blowing the white. you are fine to keep running but once you shut it down thats it you gotta fix it or you will window the block if it starts or tries to start the next time.

Whos injectors? Heavy white smoke is most likly fuel, could be blown oring or could be a broken nozzle. Fuel could look like oil coming out the turbo mixing with soot and turning black.

What turbo? If stock then it could have issues. Spin the shaft and look at the end of it and see if it wobbles like it is bent.

99% chance you have a broken nozzle.
