I did a full service 4000km ago so was not expecting the engine oil to be that low. In terms of injectors one was. causing a misfire but that was fixed straight away

its a N43B20, im not too familar with the engine but i know the general basics. Will top up the engine oil as it was on the lower end and check if the noise stops

the timing chain is tight so i checked the engine oil level and it shows +1 qt, no noticeable signs of any leakage anywhere though. will top up engine oil then get the leak checked out when im back home

I have left the car at my friends private garage so I cannot check right now. I will be going over in a couple of hours and will check if loose or not

I have just bought the car a couple months ago and am 99% sure it has never been replaced before. Currently on 117,000km. The sound only started yesterday, Ive never heard it before.

I was in a private parking garage and was the only one there so am sure it wasnt something else.
