Fine, thank you.
Let me take a look at the engine...

Roght now I'm not in the mood to remove the engine and take it apart nor remove the heads with the engine still in the car.
Is there a way to understand if the lifters are damaged without removing the heads?
Same for cam, rods and crank bearings.

So far I checked everywhere with a sthetoscope at idle and revving the engine. But the noise appears only with a little load and while driving. As long the car dosn't move I can't recreate the noise.
The noise appears after about 2000 rpm.

I also remove the injectors plugs one by one to see if the noise changes depending on which cylinder isn't firing, but nothing changes.
