he already send the turbo to get rebuilt i wanna keep it stock thats why i dont buy another engineI'll add to my previous post.
I don't know anything about gas turbos but l know diesel turbos so l'm sure it's the very same principles, an when they start smoking it's either the injectors or turbo, turbo smoke is different than injector smoke. Point is they just take turbo off and get it rebuilt.
If you don't know a good turbo shop call Cat or Cummins and they might do it or might tell you where. It's alot cheaper than $1700 and won't take alot if time.
