I actually do not know if the timing chain tensioner was ever changed, I have owned my car for just 3 months, so it probably has not been changed ever, as I said the car has 130000kilometres on the clock, but the noise completely disappears after about 5 minutes, if as it seems changing the tensioner is a 10 minutes job, I might as well do it, I will check the oil pan in the next oil change as well, in about 5000k.
