don't sit on it forever, get it fixed. its about a $35 part and takes 5 minutes to change. if you leave it go it will ruin your other mounts and leaves the possibility of kinking or breaking cooling lines because of the added movement. definitely not an immediate danger but if left unfixed will cause problems. my roommate was driving around his sho with a busted mount only to find that his upper intake had been rubbing on the hood of his car. left marks all over the intake and on the hood. good luck!
