Right Engine Mount

the sound of my car's right engine was coming. I showed it to the master. He took it off and looked at it. There was nothing. 3 days have passed since the sound was gone again, this time I went again. looked at the source, he said. We removed it, yes, the bonnet collapsed in on the side of the bush with the right engine ear. there was welded as an additional sheet. then the ear was placed in place. sound improved but repeated after 10. I'm going crazy now ...
