Knocking noise from spark plug?

---

Hi guys, have a knocking coming from the spark plug (1.8 120 K Series).
I have replaced the spark plugs, still making the noise then HT Leads and coil packs which sorted the same noise from no. 4 (last bit on video).
No. 2 is still making it, if i rest my finger on the top of the HT lead it will get louder, twisting slightly and it stops.

I have a video here to show what i mean

Thanks
