Yea, mine too. I'm an amateur mechanic from hobby only. I don't know what I'm going so I'll double check all glow plugs are working, determine which cylinders are not firing and go from there.
Flooded diesel engine :(

that looks like oil smoke in that vid, diesel would be blacker?

I'd hardly describe that as "all good". If it sounds and smokes like that you've got a very poorly motor.
Unburnt diesel gives white smoke.
I'm not a mechanic but aren't the glow plugs just to get it going, once its running the glow plugs are redundant and therefore can't be an issue.
Could be wrong
Bent con rods.
(Bent con rods will reduce the effective compression ratio. Diesels are compression ignition so reduced CR will affect the reliability of the fuel combustion causing a misfire that may be less noticeable once engine is warm or at higher revs Carry out a compression test on all cylinders Id expect that they are significantly below spec and likely different from one another)

Yea, bent conrods would not have let me run the engine?
And a as for the all smooth remark, thay was the very first time it started. After about 10 mins running. It started spewing out smoke and running very roughly... Now it runs rough from the get go.

My old man did this to a lovely TDDI Mondeo I was hoping to inherit!
Drove through a ford, hardly any signs of water but enough got into one cylinder to cause a rod knock. Wrote off the old girl
Engines will run with bent rods just not very well, like yours!

Best way to find out if I have bent rods?

Turn engine over by hand having someone look down the heat plug hole to judge TDC. Push pencil through heat plug hole until it touches the piston. Mark the pencil where the top of the heat plug hole is when that cylinder is a TDC.
Repeat on other 3 cylinders. Provided that you hold the pencil at the same angle and contact the pistons in the same manner, the mark should line up on all 4 cylinders.
If it doesn't, one of your conrods is S-shaped and it needs an engine rebuild.
As a 'new' road user (despite having a bike licence for years) insurance is expensive as it's still first year (late 20's and treated like a 17 year old). So I wouldn't go through insurance for the car costing £2,000 with their STUPID excess.
I have my Ducati Multistrada 1200S worth £11,000 insured with 4 years NCB at literally 15% of the cost to insure my car worth £2,000. I hate insurance companies
If I can't fix it, I'll have to scrap it. Will do that pencil test now. Bloody clever idea. Easy and quick way to find out just how much butt hurt I have coming my way.
It doesn't have to be much of a bend! An engine can appear run reasonably well with a slightly bent con rod, but the rod will then be subject to bending stress on every engine cycle and is likely to fail from fatigue at some point in the future.
The easiest way to check for a bent rod is to have a compression test carried out. Measuring with a pencil down the glow plug hole isn't accurate enough to tell you anything, unless the con rod is extremely bent.

Compression test is the more accurate method of course, but the pencil test is a very quick and dirty way to tell if the rods have been bent.
More than a millimetre difference between any 2 cylinders and you've got a problem. it's also free if you already have a socket/spanner to spin the crank with.
