Slight Noise | Engine

Hi guys, I have a 59 plate 1 series, 2 litre petrol. Reg CA59 APK. Good milage for age - 41,000 on clock.

Firstly I'd just like to say thanks to everyone as I was suffering with a very notchy gearbox for a few months (bought the car a year ago) and after research on here, had the redline MTM oil fitted and the gearbox is a dream now compared to how it was. Much more enjoyable to drive.

Now, I've searched as much as possible and I am unsure if its just in my head or not but the engine has a ticking sound to it. I can hear it most in closed areas (mcdonalds drive through for instance) I am unsure if it is the timing chain or not. It does not sound like this at all, is this how the timing chain sounds when on its way out?

" onclick="window.open(this.href);return false;

It has had this sound since I bought it, I didn't realise it was any different to any other 1 series until a mate of mine mentioned the noise whilst I parked up. I will take a video ASAP for you and post it so you can check it out but as it is a 59 plate, am I right in saying that the chain should not snap and it is just the annoyance of the noise? It's making me very anxious after reading threads here and if I need to change it I would rather do it now and not ruin the engine. I also believe I just missed the BMW recall which has me

Thanks for anyones help. Cheers
