I have a nissan cashqai 1.5 dci problem with blue smoke from exhaust and neat oil coming out from exhaust pipe

White Smoke = Steam
Blue Smoke = Oil
Black Smoke = Rich Mixture

Are you losing coolant?

Are you losing oil?

And my learned colleagues excellent advice should be down here.

Have you opened the bonnet up and looked at engine ?
Suggest checking oil cap is screwed on properly ?
Look at exhaust manifold is there oil spilling onto it ?
check oil dip stick is fully inserted into engine ?
Also check power steering pipes for leaks ?
Let us know how you get on !!

Sounds expensive. Blue smoke usually means oil in the combustion chambers, from worn out rings. Anti-freeze inside means leaking hoses or heater core. Not sure where the driver-side tire comes into this, unless that is where the smoke is coming from, in which case that likely a problem with a seized brake caliper.

Could be oil smoke, it's white with a slight blue tint. If the engine was not properly maintained or abused, the piston rings can wear. Worn piston rings might allow oil from the crankcase to pass into the combustion chamber; there, it will be burned and pushed out the exhaust.

Check your oil pan,may be leaking.Or your pistons are bad,what does your spark plugs look like.

White smoke from the exhaust indicates engine coolant entering the cylinders; usually caused by a blown head gasket or a cracked head. Continuing to run the engine will allow coolant to go through the engine internals and destroy them.

check engine light on

Have you checked your oil? If it is low add the oil but blue smoke usally means the motor is using oil could be the rings or broken rings you will have to check the compression in the cyl.

There are indeed traces of oil coming out of the exhaust. Blue smoke is burning oil. Grey or white smoke is usually coolant/water going through the engine. This can be caused by leaking head gaskets, valve guides depending on the engine, excessive blow-by, etc. Large amounts of oil are not good; and water is even worse. I would look at getting the head gasket replaced. The loss of power is because neither oil or water likes to burn, and once your engine clears it out, it probably runs ok for the rest of the day. Then I'm guessing the next morning, it comes back. This is an urgent fix, because prolonged leakage can damage the engine block, head, or both.

Typically, White smoke from the Exhaust Means that the Motor is Burning Oil. Keep an Eye on the Oil level and let me Know.

White smoke usually associated with water or moisture. it doesn't take too much water to produce white smoke. check

1. cloudy oil under oil cap
2. leak through gasket from cooling jacket to combustion chamber
