SOURCE: Smoke from exhaust... toyota rav4 1996

Welcome to FIXYA

There in only 1 thing i can think of where the white smoke is from it could be anitfreeze if so it would mean a cracked head or a bad head gasket if it gets worse then you have a big problem but if you check the water level and it looks fine then you should be ok for a while

if it was black smoke or a real dark gray then it would be oil


i hope this helps you out have a good day

SOURCE: black smoke coming out of the exhaust of my toyota

It is running rich, too much gas possibly plugged air filter or PCV issue. May just need a tune-up. Blue smoke would be oil burning and White could mean headgasket or worse....

SOURCE: what causes white smoke exhaust system 1998 toyota camry v6

The likely cause is coolant leaking into the cylinders due to a failed head gasket. You should be losing some coolant and need to top it up so check the level. You will also find that coolant is finding its way into the lubrication system and "contaminating" the oil.
Remove the dip stick to check the oil and if you can see a whitish substance in the oil you have coolant in the lubrication system which is is leaking through the failed head gasket.
You may also see traces of oil in the vehicles cooling system so look there also.
The only fix for this problem, once properly diagnosed, is to have the head removed from the engine and a new head gasket fitted. The head would also need to be checked carefully in case of cracking and in any event would most likely need to be machined by a head specialist before being refitted.

The `cause of the failure is unknown but if the vehicle has ever been operated with an overheated engine (due to problems with the cooling system) this is enough to blow the head gasket and to potentially damage the head on the engine.

Not good news I'm afraid so please get it checked out and properly diagnosed with a reputable auto repair business.

Black smoke emission


Sound like the oil rings have collapsed. Assuming this is a petrol engine, check your spark plugs for oil and carbon. If they are dirty then you probably need an engine overhaul.

My sienna was emitting black smoke. scan codes P0171: Generic system too lean back1 P0325: Knock sensor 1 circuit back 1 or single sensor P1130: Toyota air fuel sensor performance bank1


The lean code is making the computer dump fuel(black smoke). First check vacuum lines( on yours I would replace all them, it's 17 year old), Listen for any hissing noise. Being a 98, I'm not sure if you have a MAF sensor. But also make sure all the air filter hoses are connected and tightened down.

How I do my Toyota sienna 200 emit black smoke,slow speed often.


loss of engine power. its called, and may stall, it will soon,.
the black smoke is very very rich fuel.
and the dash board, CEL glowing running, telling you to Scan the PCM.
so do so. ok seems you did?
next time post all DTCs, never tell me what they mean, i look them up
in real books, real Sienna 2000 books, not web rumor bs.
which engine?
my guess is
3.0 L 1MZ-FE V6 (1998-2000) This one.
3.0 L 1MZ-FE V6 (01-03, VVT-i)
The V6 DTCS, we need all DTCs thrown. by number
like P0300 or the like.
is 200 = 2000 year? 1998 to present they are made.

1999 Toyota Camry grey smoke from exhaust


If it is grey smoke it sounds like steam which sounds like the cylnder head gasket is bust and needs replaced - if it has overheated then the worse case sceanrio is that the cylnder head may need reground or replaced. If the "smoke" is black then its burnuing oil and the seals are bust - much bigger job and more $'s.
