John is correct. If there was any damage to the block it was replaced. But in most cases the service rep gave the green light for an entire short block to save warranty time. It was usually an easy sell to get the rep to go this way and it was usually better for the customer as well. I've seen short block assemblies replaced because of a noise that could not be isloated. Seems hard to believe but again it was many times based on warranty time paid versus cost of replacement parts.
