- Blue smoke: this usually suggests that oil is being burnt due to worn valve seals, a damaged PCV valve, or piston rings.
- Black smoke: black smoke means too much fuel is being burned or not burning properly. This can happen if the air filter is dirty, the fuel injectors aren't working right, or some engine sensors are broken.
