Video of tapping noise [youtube.com]
Have just noticed this strange noise coming from the head of the engine louder on cold starts can’t really hear at higher rpm car feels a bit slower (but may be because I’ve got my beemer back which is a lot faster and have been driving that for a week or so)
Noise doesn’t go away but is quieter when warm any ideas?
