Hi. I drive a Cruze 1.6L 2015 model. It is leaking oil after 150000 service done by an acredited service provider. So far we replaced: Coolant Gasket Seal; thermal housing; thermostad housing return pipe; oil filter (again)... But the burning smoke + smell persists. The actual leak underneath the car is minimal (small drips occasionally). The smell is worse when the car is idle in traffic, or just leaving from a traffic light after stopping for a while (especially at a steep angle). Any shared experience or advice? (I drive inland in South Africa - Gauteng if that helps).
