If there is an oil leak inside the engine compartment of the vehicle. The defroster could have some of the smell go into the cabin of the car. The engine should be checked for any oil leaks.
could be a gasket that has finally gaveway and the smell of oil is the oil burning on the engine.
It's the oil that you smell burning.
Oil that has somehow gotten onto the manifold of the engine will produce this smell. Any oil leak in and around the engine will produce this.
it leaks oil.
You most likely overfilled with too much oil. That burning smell is your burning oil. White smoke can be indicative of many things depending of where it is emitting from, but the fact that this only happened after your recent oil change almost certainly points to overfilling.
Sounds like you've got burning oil, probably due to a leak.
head gaskets are probably bad and leaking oil onto crossover pipe .
yes
oil leaking on the ex man fold need to fix the oil leaks
Defrost uses the a/c, if it doesn't smell the same with a/c only on. The smell is coming from the blower motor. Bmw's for example have a problem where the blower blade contacts the plastic housing and causes it to rub/melt.
when changing the oil sometimes oil can be spilled on the engine block. as your engine heats up it causes this smell. it is completely normal
New car smell? Maybe because of the leather seats (if you have leather seats..)
