318 diagnosis

@AJ/FormS ,
video doesn't tell whole story. Yes, kinda looks normal, and does have alot of condensation at startup until it gets hot but when getting on it on highway...it smokes enough, people get out from behind me.
I can drive normal speeds and not really see any smoke. This has been frustrating to diagnose.
I believe my best path forward is the steps in post #11...unless someone has another thought.
