Black smoke from exaust pipe - 2004 Toyota ECHO

Is it white smoke or vapour/steam this could be signs of head gasket failiure

blue smoke mean engine is burning oil bad cylinder piston rings

is the smoke coming from under the car or out the exaust pipe?
under the car ! you have an oil leak and its probably landing on your exhaust pipe which by the way can ignite and go on fire if the pipe gets too hot. if its out the exaust ! computer or air intact problems. worst case: rings are bad and oil is mixing with the gas in the piston chamber. Hope this helps a little good luck and God Bless

Are you saying you have smoke coming out of the tail pipe ? Or is something dripping onto the exhaust pipe and burning ?
If the smoke is coming out of the tail pipe, is it blue, white, or black ?

petrol or diesel

LOOKS LIKE YOU NEED AN O2 SENSOR I'LL BET YOUR GAS MILAGE SUCS TOO O2 IS LOVCATED IN YOUR EXAUST RIGT PAST THE MANIFOLD THAT IS BOLTED TO YOU ENGINE ITS COMMING RIGHT OUT THE EXAUST PIPE SIDE REPLACE THAT AND IT SHOULD TAKE CARE OR YOUR BLACK SMOKE

if engine is running without missfire check catyletic converter for plugging also very rich running will cause exhaust to glow but will cause alot of black smoke from tail pipe I dont reccomend driving vehicle till exhaust or rich running is fixed can lead to engine failure

is it leaking, or burning in the combustion chamber? Comming out the tail pipe? Blue smoke is oil, white smoke is water, black smoke is carbon. Smell your exaust; smell like "prestone"? Does the engine over heat? My guess would be a bad head gasket. Is the oil a light brown color?

Either your valve seals are bad or you piston rings are wore out. I would say it is the valve seals though.

it is aproblem if smoke came out the pipe when engine started.
