Good evening, I have produced a V70 T5 automatic from 1999 which, unfortunately, depends on the speed, produces a flapping / rattle from the upper part of the engine (is my feeling anyway). The noise is the loudest at 2000 rpm. It does not need water or oil, does not smoke and has my sense of normal performance. I recently made a motor flush with subsequent oil change with original Volvo parts and good oil and that felt a bit of relief, meaning the noise is I already drove about 200 KM with the sound and therefore I conclude that there is no bearing damage, otherwise it would be completely over. In the old oil there were also no chips or especially a lot of dirt, a bit of oil coal, that was everything. It is an engine with variable camshaft adjustment, I wonder if it could be because of it. I uploaded a video once and I hope you can hear something about it:https://m.youtube.com/watch?v=wstqDNtRx7s I thank you in advance for your help! Greetings, Gregor
