E90 320d m47n2 engine problems

Hello, i have just removed the injectors, intake valvr and egr.

I have posted pictures of a video framerate of the injectors.
They all had oilspill except 1. And one of them had extremlet much oil on it..
- what does this mean?


The egr valve is full of oil and big chunks.
- clean and i can use again?

The pipe going into the egr valve was spitting oil like looads.. (statted engine without it connected.
- what does this mean?

Overall, the engine is shaking alot.. extremly much until i reach 2.200+rpm..
It once came extremley much blue smoke from the exhaust
- does this mean its the top block of engine leaking coolant?

Is it worth to find the problem or should i just buy a new engine?
I prefeer to locate and find the problem..

I know thats not suppose to look like that, i think you will have more luck on German forums where there are many specialists going through and helping people with issues like this, you will just have to use the translate for everything you type and read =) did you end up sorting all this out? what was it?

the M47 engine was installed until 2007/03 on 320d
so many of these cars are with mileage 300000-500000 kms
the injectors are tests on bosch testbench at authorized bosch shops
