Yes. Every car does this. Unless you prime the car to build oil pressure after a change you are essentially starting a dry motor that takes a second to build oil pressure into the heads. This clunk from the car sitting is essentially the same thing. I don't know if people can actually see my posts as it's been written here before as well. IMO it's not a big deal just an annoying noise.
