so..... oil leak and turbo failure.......

[mark_airey]

K14 is as good as the T2 and a great turbo, its the same size as a T2 and massively underrated IMO (ruans took massive amounts of abuse IIRC)

I would have to say that the oil on the block would probably be from the rocker cover as that is fairly normal and if your using huge amounts of oil and its coming out of your DV then the turbo seals have probably gone on the compressor side sending all the missing oil through the engine

I would say that you need to, a) replace the turbo before it goes properly and the engine runs away on the oil, b) changer the rocker cover gasket, and, c) remove the DV because they are silly on a diesel
