Depending on how accurately it is being measured. If it is truly 4.8 that is worn .006" or more and is way too much. I am assuming you are using a caliper, a micrometer is more accurate. With the crank worn that bad the rod will also have wear and you could have .010" total slop which will not last long. I consider .003" total slop or worse a back up engine.
