Whenever I drive for a bit, sometimes after gettin on it, or after I stop a stop sign or a light I get burnt oil smell coming from my vents. I have no clue where it's coming from? But after a bit it goes away usually only smell it once after a couple min of first driving it. Anyone have any ideas? my mods are u/d pullies, T/A, and cai. Gettin kinda freaked about it. Any help would be appreciated.
