About a month ago I swapped cylinder heads and checked the turbo then, no play, free spin on the vanes. Will look again when I tear into the actuator. I have not heard any unusual turbo noises, whine or grind since the loss in boost.
Other than physically not working, are there any internal gaskets that could blow in the turbo causing this and not showing any external signs?
