I made all the tensioners and belts with my m54b22 motor and since today I hear a funny clack from the engine compartment. I started the engine without the belt the clacking was still, all spark plugs are also fixed. I also add a link to how it sounds https://youtube.com/shorts/JPT_LsLytZo?feature=share The car is currently logged off and I never let it run for a long time almost every 2 days I hit it and run for 5 min, this can also crack cause?
