Besides that the injectors pulled out were covered in oil, explaining the diesel runaway which eventually hydrolocked the engine with oil filling up combustion chambers.

I will be getting a new valve cover to play it safe not risking it being warped.

So to sum it all up:my car had a partition leaking which shorted two injectors;around the same time the valve cover created the oil seep through the boost runners which in turn clogged the DPF and SCR.
