After how many kilometres must one change a DIESEL filter in a 2.5 D4D Diesel engine 2016?

a D4D diesel engine in a TOYOTA HILUX
well all filters good (air and fuel)
all diesel fuel lines purged of air and at spec pressure
good fuel pumps.
glow plugs not dead,(all)
get the service manual and it covers injector changes steps.
fuse good? to pumps. (lift pumps etc) many pumps can not pump air so must be primed.

White smoke on diesel engines, means water in combustion chamber. Blue smoke means oil.
In what condition was the filter you removed? How bad? Temperature issues? Missing coolant maybe? If yes, you might as well have an internal leak. Some gasket maybe. Check all you vital fluids levels. If anything missing, take the time to empty the engine oil on a can, and check the colour. If it will look like chocolate brown, then you do have a leak from the inside.
