Hi there. My turbo blew, which part, I don't know but there is smoke everywhere. Not the usual smoke like blown gasket, worse white blue smoke. I want to drive it too get it repaired, but it's almost 80km from where I am. Will this be possible for me, will it use too much oil? Can I make it worse? Please assist

Hello,

Turbos are not too complicated. Basically they are two shaft, an input and an output, which are linked together by a set of gears. Each shaft has a gear with the output shaft having the smaller one. This gear reduction is why the compressor wheel spins at such a high speed. You have a case to enclose the gear box and another to house the impeller wheel that spins the input shaft from exhaust that spins the impeller wheel. When a turbo "blows", it is usually the output shaft seal that fails and lets engine oil that is run into the gearbox to lubricate the gears out into the compressor wheel where it is compressed with the incoming air and then into the engines combustion chambers through the intake manifold and burned in the normal combustion process. If you keep oil in your vehicle, and make sure you don't run your vehicle out of oil you should be okay. Also try to stay out of the turbo, as it is only actuated when your waste-gate opens. Baby it, keep a good eye on your engines oil level and you should make it to the shop. Please let us know how everything turns out.

Thanks,
Alex
