the turbo blew half away around a roundabout, but engine didnt runaway. I turned the engine off after realising it was clouding with white smoke behind and pulling off into a lay by. so couldnt have been running for more than 15 - 20 seconds after the turbo giving up. My question is. now that the dipstick isnt showing a oil level at all. is it likely the engine is now nackerd as a result of oil starvation? i havent started it since. thanks.
