Eventually, your valves will get a nice coating of baked on oil and your intercooler bricks and supercharger will have a nice layer of oil coating them reducing efficiency. It may take many years or miles but not having a catch can will eventually show up long term. Before you ask why GM didn't install one from the factory, its because its another maintenance item that they don't trust the end consumer to maintain properly...meaning it must be emptied every so often.
