Good evening, everyone. I would like to ask the x300 experts for some advice. For a few months now, I have noticed that my xj6 3.2 makes a strange ticking noise when idling.When i start the engine for the first time in the morning (cold) i don't hear any noise.During warm up the noise increase. It sounds like a valve noise, but I can also hear it in the lower part of the engine. Someone told me it might be cracked exaust pipes. Recently i welded a cracked exhaust. But the noise still remains the same. I recorded the noise. Maybe it is normal and I am worrying for nothing. Let me know what you think. Thank you very much.

There is a TSB on the timing chain tensioner upgrade that ends up having a big cast arrow on it

I already replaced the upper chain tensioner three years ago.
