I don't recall any failures from Lucas, But.....If I replace a HPOP or any work on the high pressure oil system outside of a ICP sensor, It's getting an oil change anyway! Lucas Oil Stabilizer usage could be a regional thing because I don't see it often??
The VGT Garrett Turbo on the 6.0L is VERY similar to the VGT Garrett found on LLY/LBZ/LMM Duramax trucks. They are pretty simple, Movable vanes connected to a unison ring that's oil actuated via solenoid is the only difference compared to a fixed turbo.
Duramax VGT"s can have issues with sticky vanes & unison rings as well, Just not near the frequency of the 6.0L's. I don't have a concrete theory as to why that is......But, My Duramax goes through "cleaning" cycles by opening & closing the VGT Solenoid any time the truck is idling in park.
The 6.4L Powerstroke Borg Warner compound set-up has one Turbo that's VGT.....Just a different approach to actuation vs the Garrett designs as it uses an electric motor.
