The turbo is a rebuilt van turbo. There is no oil in the fuel bowl and its not missing or blowing white smoke all the time. All gauges and temps are good. Any ideas? Could it be chip or injectors or what?
I have come to the conclusion that running a compression test would be a good start for you. If lead me straight to my white smoke issue.
