Nissan Murano smoke emitted every time the engine is cranked on Nissan Murano

Some Nissan Murano owners report experiencing smoke emissions every time the engine is cranked, which can indicate serious underlying issues. Blue smoke may suggest worn piston rings that allow oil to enter the combustion chamber, while leaking valve seals can also lead to similar blue smoke upon startup. Additionally, white smoke could point to a coolant leak due to a cracked cylinder head or a blown head gasket. Some owners have noted black smoke, which may indicate a rich fuel mixture caused by problems with the fuel injectors or the air-fuel ratio. It is crucial for owners to have their vehicles inspected by a qualified mechanic to accurately diagnose and address these issues, preventing further engine damage.
