Agree. 2k rattle every coyote I'm ben in or driven. Idle tick was after first oil change. Sounds like metal going through heat cycles or typewriter or bbq igniter. The only time I hear it is when sitting in front of my garage but it's not every time. Sometimes it's going crazy and other times silent.If you're talking about the 2K rattle or other such noises, then I completely agree. I'm sure they're normal.
However, the hideous typewriter tick is different. Not all engines make it. And those that do make it, only make it after the first - or sometimes second - oil change. Never before. So it doesn't look normal at all to me. Something abnormal definitely happens to some engines when the factory oil is replaced.
