Hello everyone,
I am the owner of a 2010 Mazda 6 2nd Generation 2.2 MZR CD 125.
I have a problem with the engine. there is a fairly loud knocking noise (see video) that has appeared. I have no power loss. This knocking noise follows the rhythm of the motor.

Here is a list of what has been done to the vehicle :
Have you an idea of what the problem could be ? Maybe someone had the same problem ?
Thanks a lot for your help !

Here is a list of what has been done to the vehicle :
- timing chain -> change
- accessory and oil pump pulley ->
- Alternator check (start without and always the noise)
- Injector controlled by Mazda
- Valves -> OK
- Connecting rod and bearing OK
Have you an idea of what the problem could be ? Maybe someone had the same problem ?
