Exhaust manifold leak, BKD engine

Good morning.

Due to acceleration and idling issues, I have an appointment at the workshop to have the throttle body checked/replaced. During yesterday's inspection, I discovered a leak in the intake manifold.
I will have the clutch replaced as soon as possible and hope that this resolves the jerking problem.
In the log, cylinder 2 shows occasional misfires, and at idle, it has a fuel quantity reading of 2.99 mg/hour.
The intake manifold is covered in soot on the right side, near the two middle cylinders.
Is that the intake valve for cylinder number 2?

Thank you.

No, that's cylinder number 3.

Edit: aside from that, you mean the one on the right side when looking at the engine from the front, and not the right side on the passenger's side.

The engine is mounted transversely (or sideways).
Looking at the engine, I see the timing belt on the left side. Counting from left to right, it's the third cylinder.

Yes, then it is indeed the 3rd cylinder, because the counting starts from the side that delivers power.*

* Also, a quick note for the future: Not every manufacturer (like French ones, for example) handles it this way!

Unfortunately, cylinder number 2 is clearly the problem.
Let's see what happens after the seal replacement.

There are also German companies that don't operate in that way, for example, Deutz.

Take a look inside the intake manifold once the blower is removed. You might be able to see the condition of the valves (and how dirty they are).
A value of +2.99mg is more likely to be attributed to issues with the pre-combustion chamber (PDC). Engines with an added intake manifold typically run smoothly in low load and low RPM ranges, as there is relatively ample time for filling the cylinders through the constricted cross-section.
