If the black smoke is discharged from the tailpipe then the engine is running too rich and the engine needs a tune up.
If white smoke is discharged from the tail pipe especially when driving off at the stop lights then either the valve guides or the piston rings are worn then the engine needs these parts replaced and you need a mechanic to fix the engine. I suggest you get a quote first.

White smoke on cold start up

Good news and bad news.
All cars & truck with gasoline engine can emit white smoke on start up.
This is water vapor evaporating .
You have a problem if you have white smoke after the engine is warm, unless you are way up north and the outside temperature is really cold.
Also, keep close watch on the radiator to be sure you are not losing radiator coolant ( perhaps a leaking head gasket ) and the motor oil on the dipstick (should not be "milky" or the color of coffee w/cream)
as that could indicate water in the oil, which is really serious.
God bless your efforts.

When smoke testing a 2002 Jeep Liberty 3.7L for a small evap leak the only smoke we get is coming from the filter on the filler neck. Should we be getting smoke there and if not is it safe to assume that...

Not sure what your referring to,but if it
is a solenoid, you have to command it closed,
to smoke the system,if there is a chance it vents
to the outside atmosphere, with the ignition & motor

You assume nothing

You should have a diagram of the Evap System
& study that

Then you decide how to go about testing it

Any part that your scan tool can't actuate, you can
with battery voltage direct to it

01 dodge intrepid blowin white smoke

if its white smoke and its not due to a drop in outside air temp then this indicates that the motor is burning engine coolant,,which could be caused by a bad head gasket,cracked head,leaking intake gasket.have a block test done to see if there is combustion gases in the coolant.

Smoke is coming out of the tail pipe even when the car is at driving temp. The smoke is not black

is it a bluish grey color smoke? if so then your motor is burning oil. you will need atleast a ring job to solve this.

is it a white smoke? if so then it is evaporating water, whish could be any number of things the worst being a possible cracked head or blown head gasket. or it could be something as simple as moisture in your muffler evaporating.

check your oil and coolant level, check for milky looking oil.

hope this helps, have a good day.

Land rover 2.25 diesel 5brn.white smoke from

White smoke is indicative of burning antifreeze, if your not using antifreeze then it is condensation when the motor starts however if it does it all the time and it's not cold outside you have another problem.

White smoke coming out tailpipe

If your intake gaskets are leaking, when you dump soapy water on the gasket, it should bubble like crazy ( when it's running). If you can, run it with the rad cap off and watch for bubbles. If it keeps bubbling, you probably have a head gasket problem.

Smoke from under engine

You need to replace the spark plug tube seals. Buy a valve cover gasket that comes with the spark plug seals. This should solve your problem.

White smoke or steam coming out of exhaust pipe,

Its funny that everyone has solved the problem without any answers to critical questions. In this case, everyone is right and everyone is wrong. ONLY careful testing and observation will determine if there is an actual problem. I do not solve problems just to be first. Even in a hands-on situation I refuse to jump to conclusions before testing, otherwise you run the risk of at best, "chasing your tail" or at worst, tearing into a perfectly good engine to prove nothing!!!
Happy New Year!!!!
