Smoke coming from oil filler cap on RR sport 2014 3.0 autobiography diesel and a knocking sound

When you said knocking I was imagining a loud knocking noise.
All a bit irrelevant now since we are talking about different engines.
As a side note they still run with snapped crank, apparently.
Since I don't have a Range Rover probably best to wait for someone else to answer who has experience with that engine.

The 3.0L TDV6 is the same basic engine as the 2.7L unit fitted to the D3 and early RRS, but with a longer stroke. The 3.0L is more likely to suffer bearing failure and crank failure, as the oil pressure is pathetic, and the boost comes in very early, exactly when there's little oil pressure to support the bearings. It's a garbage design, and very unreliable as a result.

Only what I read on here, badly though I imagine.
Do they actually crack in half or do they just crack a little bit?
The original post came across as a knocking noise and smoke coming out of the engine, so not sounding too good.
Didn't realise he had been driving it like that for six months.

Hi mate it is notoriously difficult to diagnose taps and knocks without hands on, if you're driving it would seem it's not bottom end as someone mentioned it would have given up by now big ends normal knock more when your foot on the throttle but quieter when off but not always you're probably going the correct route by getting a specialist to look at it as you have a multitude of possible contributing factors but make sure you tell him the full story he should be able to run live data etc will keep my fingers crossed its injector related but I would like to know the outcome as your never to old to learn good luck
