Hi Geoff, The symptoms you describe certainly point to the turbo. The turbo is basically an air compressor. It is operated by spinning a turbine with the hot exhaust gas which is joined to an impeller via a shaft. The shaft runs on a special floating bearing which is lubricated with pressurised engine oil. There are two special oil seals sealing that central shaft section from the impeller and turbine chambers. If either is leaking, oil will leak into the combustion chambers and result in excessive smoke. I do not know if repair kits are available where you reside, they are not available here and special seals are required. You may need to replace the unit with a reconditioned or a new replacement. Regards John
Water in combustion chamber makes white smoke--suspect that the head gasket is leaking water into the chamber. If oil leaking around turbo, it may have a bad bearing and bad oil seal. Check waste gate valve and control.
hi there, there are chemicals on the market that will soften up the seals but these take time to work i would suggest changing the turbo, you will also have to remove the oil from the exhaust system this can be done with other chemicals like an upper cylinder cleaner feed directly in to the air intake but only after the turbo has be fixed
