IF I understand you correctly, you are attempting to re-start the engine STILL with (probably) fuel-diluted oil

STOP

IF the engine isn't already wrecked, this is your second opportunity to wreck it.

DONT

Damage in such cases can be severe, as in con-rod through the oil pan severe, but you would probably have noticed that. Any loud noises before it stopped?

If there is no obvious dramatic damage. possibilities might include

Seized piston, due to oil starvation, but I gather its still got oil (albeit probably dilute) and is still turning over

Broken piston rings, causing loss of compression

Cracked cylinder head, ditto

Broken fuel pump, no longer supplying the official fuel ration. This wouldn't necessarily stop it running unofficially on the diluted sump oil, but you dont want it to do that.

Turbo failure, as you suggest. That'd be good, since your actual engine MIGHT be relatively unscathed. and it could get you off the hook entirely, since turbo oil seal failure could have supplied the engine with the fuel to overrun. Cloud of white smoke could be consistent with this.

Bit of a coincidence that you've been fiddling with the injectors, which are probably more likely to have raised the sump level. but it might serve as a cover story.

Before doing anything further, I would work out some IA's for stopping another engine overrun. Possibilities are stalling it (only applies to a manual transmission, which you might break) and suffocating it, either by blocking the air intake, which may not be very accessible, or using a CO2 fire extinguisher. The last one sounds safest to me.

MIGHT be time to call in the pros. I wouldn't, but then I've lost vehicles through stubborness

The oil stick shows the oil has very high, which it is not, so im wondering why the oil level should read as high?

I think it's a common problem for old diesel engines. Unburnt fuel makes its way into the sump, which is probably why some people make the absurd and impossible assertion 'my engine uses no oil between services'. What they don't realise is that as fast as the oil is being burned, it is being replaced by fuel. As most people don't run their engines beyond 150,000 miles, the resulting reduced engine life from its increasingly compromised lubricant is not a problem, unless the sump gets so full of the fuel/oil mixture it 'runs away' and lunches itself.
