Burning Oil Smell from Engine Bay
A burning oil smell coming from the engine bay of a 2019 Hyundai Elantra typically indicates an oil leak that is dripping onto hot engine components, such as the exhaust manifold. This can be caused by a valve cover gasket leak, oil pan gasket leak, or a leaking oil filter/cooler. If not addressed, it can lead to low oil levels, engine damage, or even a fire hazard.

Possible Causes
Valve cover gasket leak – oil seeps onto the exhaust manifold, creating a burning smell.
