Hyundai diesel

[Dick]

Hiya chaps, just checked the oil on a friend's modern hyundai thing, the level is twice what it should be and stinks of diesel.. any ideas.. I'd have thought any unburnt fuel would have gone out the exhaust

Most likely passing the piston rings Rich, either worn rings or overfueling / faulty injector. The only other thing that could be suspect to my mind is the fuel pump if it has a direct passageway by which fuel leaking from a worn seal could enter the crankcase? but I don't know the Hyundai engine.

Fuel dilution of oil could also be worsened by lots of cold running, long periods of idling,..... and frequent short trips if its a modern DPF type engine because interrupted Regens can supposedly cause overfuelling if it starts the regen cycle on a short trip and then gets cut short.

A few thoughts anyway.... might all be wrong lol.... but whatever is going on the oil needs dropping sharpish and then new stuff in and a good eye keeping on it.
