you shouldnt be able to pull away rubber from the metal piece

sounds like you may have a crack - mount needs replacing

how many kms has your car done?

timing belt changed? tappets adjusted? checked valve clearance?

so many variables - and i hate to say it but could cost you abit to get em fixed.
