Yes. I did a test. The difference between the cylinders is 0.5 kgf / cm2

Another possible way to help with diagnosis would be to pull the injectors and inspect the tips of the nozzles

That's the difficulty, that soot on nozzles and washers is the same. Even after a long trip.

If you still can't narrow it down to a particular cylinder via injector inspection or a leak down test, I would suspect the pump and try swapping with another one.

It may be necessary to do so
I have a question:
what if the engine has a different degree of compression in the cylinders? If anyone cylinder protrudes from the block less than the others. A leak test won't show this.
Can I try to reduce the thickness of the washers under the injectors?
