Yes, that part can be replaced. It's obviously a separate part that is screwed into the pan since it's steel and the pan is aluminum. I've always known them as an "oil filter adapter" since it's what is used when you're adapting a filter to a filter boss, such as on an aftermarket remote filter kit, etc.
...After a little digging, it looks like it is part number 12552357 and the proper name for it is "fitting" or "connector". Do your research to confirm as there are different threads sizes between the years.
Thank you for quick reply and pointing in right direction. Looks like that part number isn't for the 6.2L engine and I can't find anything on RockAuto, GM Parts Direct or Amazon for my year/engine under oil filter fitting, adapter or connector. However, since I know what to call the part I'll ask local dealership tomorrow if they can get it or know the p/n. I'll report back once I get answer.
