Update of the noise from a Volvo D12D engine

Five years and half has passed since the first video of this engine. The engine still makes the same noise and nothing has been done to the engine trying to find out the source of the noise. Blow by is minimal and the fuel mileage has stayed pretty much the same. So the noise probably didn’t harm the engine at all just like what most people has commented on the original video.
