I you absolutely can't get that zinc out (I have heard of others who have forced it and broke the heat exchanger........) and the engine doesn't have any cooling problems now, it might be a good idea to just flush the heat exchanger with muratic acid or vinegar. I would probably just use vinegar if you are not experiencing problems. I don't see why you couldn't get several years of use out of it, especially if you flush it at least once a year.
