What does blue smoke mean - 2002 Nissan Altima

What color smoke white means coolant, blue means oil, black means burning too much gas. Who did the head gasket? Check for oil in the coolant. This could mean a bad head gasket install or a cracked block. If you have blue smoke you have worn piston rings

Blue smoke means burning oil most likely due to worn piston rings. Black smoke means car is running rich too much gas being burnt

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.

Black smoke means it is running rich (too much fuel). This is controlled by the ECU and it could mean the temperature sensor is faulty.

Blue smoke is oil, and it means either worn piston rings (a compression test will reveal this), or leaky valve guide seals.

Pure white smoke is water, and may mean a leaky head gasket (again a compression test, and a test for combustion gases in the coolant) or a leak from the water jacket into the inlet manifold.

Smoke from the exhaust? That's an engine problem. Blue? White? Black? Yes, it matters....
Blue likely means rings or valves. (expensive)
white likely means head gasket (coolant invasion)
black likely means fuel problems.

Generally blue smoke means burning oil, black smoke is rich mixture, white smoke is steam from water or coolant.

Good luck with the carb!

blue smoke from any internal combustion engine indicates it's burning oil along with the air/fuel mixture........this can be caused by gaskets or seals. in higher mileage engines it can be caused by worn internal parts

Blue smoke means burning oil. Black smoke means running too rich (too much fuel in the air/fuel mix). If it is blue smoke:
If it blows blue smoke only shortly after starting, it means oil is leaking into the cylinders from above, through the valves. This us typical of older engines, and can be repaired without removing the engine from the truck (although it is still expensive). A 2008 should not have this kind of problem.
If it blows blue smoke all the time, it is bad piston rings or scored cylinder walls. Oil is leaking from below up into the cylinders. This is bad news - any solution will require removing the engine from the truck and complete disassembly (i.e. a rebuild). No engine oil treatment will make it go away, regardless of what the label says.
It is very, very rare in modern engines for a well maintained vehicle with less than 100K miles to need a rebuild. Damage such as this usually comes from not changing oil AND the oil filter often enough. 3-4000 miles for conventional oil or 6-8000 miles for synthetics. If using synthetic, be sure to get a high quality filter designed to be effective for the synthetic oil change interval.

if your blowing blue smoke has nothing to do with turbo
blue smoke means your burning oil
which means u have bad valve guides or bad piston rings
you will need a motor rebuild

Blue smoke is caused by engine oil entering the cylinder area and being burned along with the fuel air mixture. As with the white smoke, just a small drop of oil leaking into the cylinder can produce blue smoke out the tailpipe. Blue smoke is more likely in older or higher mileage vehicles than newer cars with fewer miles.

This could mean a cracked head or bad gasket....It costly
