Any takers on this. What would you think is failing in the fuel system to block the injectors like this?

I had problems getting it out the cylinder head. I asked the injector...

1/ using a small slide hammer, please come out. That did not work,

2/ Using a medium sized slide hammer, I said please please come out, that did not work either.

3/ using a very heavy duty BIG slide hammer, I then told the injector, I done being polite and asking, get out now

You can't "unbreak" the broken,you can only break the unbroken to break the break of the unbroken, for me, you cannot unbreak me, for I am already broken,so you have no need to break the break because I am not unbroken.

We need to open a dedicated "Ask the mechanic" area for you, injectors don't talk much..

Ask the Technician David. People are multiskilled thesedays, mechanics back in the day did just mechanical repairs, today we're expected to know it all

If you expand the picture and look at the nozzle you'll see the nozzle has distorted, which I'm to understand is because the spray holes are blocked and this has caused significant increase in the injection pressure, therefore distorting the injector nozzle. The reason the injector would not come out is because of the distorted nozzle trapping in the cylinder head port. The injector was loose by hand but could not be pulled out.
