My KZN130 3lt Auto Turbo has deconstructed itself with much predjustice! It has been sent away to be assesed for possible overhaul, this is likely to cost around £500. Given that my truck has 170,000 miles on it and we don't know if the meltdown has damaged the rest of the engine - would I be better off replacing the whole engine? Does a secondhand engine usually include the turbo? Or does anyone have a good turbo, ready to bolt on, for sale? I need to be up and running asap as this is my everyday work vehicle.
