Hello. If the engine is running fine but the knock is consistent it may be a few different things. It can be coming from the camshaft actuator or it can be a rod knock starting. I have also had a number of engine mounts fail on this vehicle and cause this. I usually listen to each area of the engine until I can pinpoint where the noise is coming from. If you need to have this engine knock checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this noise.
