There's a rattling sound my car makes when it's cold started and goes away once it warms up but when im accelerating I can hear the rattling but its not as loud. It's a 2016 Subaru BRZ, recently did a baffle plate and oil pan replacement. Car runs fine its just the rattling is loud. I tried searching it up but no one seems to have the same problem where it would rattle at cold start, almost disappear once its warmed up and come up again when its accelerating and decelerating high rpm to mid rpm levels~
