Is it just when first started or all the time? Is it smoke or steam? White smoke at start up is normal and ok, just unburnt gas from the choke, Steam on the other hand is bad news, head gasket time, Check for oil floating on the top of the radiator, check the oil level, see if it is overfull, wit water. Check the compression on each cylinder, it will tell you if it has a blown head gasket and which one it is. Hope this helps.

SOURCE: White Smoke From Tail Pipe/Exhaust

It often means that you are burning antifreeze. You asked if it needs antifreeze, have you noticed any leaking out of the reservoir tank while you are running it? Sometimes when the head gasket goes it will produce a passage for the antifreeze to pass from the capillaries into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear sparkplugs and the radiator cap. Fill the radiator and then push some air into the sparkplug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling. Also check your oil for discoloration. If it is a brownish color it could mean your oil and antifreeze are mixing and has the potential to damage your bearings

SOURCE: White smoke coming out of the tail pipe .

White smoke is caused by water and or antifreeze entering the cylinder...If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
Good luck..i hope this helps.... please rate me a fixya

SOURCE: white smoke coming out of the tail pipe after

White smoke continuously blowing out from the tail pipe ? If it is only at the cold position it is normal, if it is always coming out it means oil consumed & compression is week. spark plug frequently needed ? If plug frequently shorted u need to overhaul or need to add oil treatment for increase viscosity.

Smoke coming from engine


Where is the white smoke coming from? Under hood? Out tail pipe? If excessive white smoke from tail pipe, suspect a head gasket failure which in turn will fill the cooling system with exhaust pressure forcing the coolant to come out of the reservoir and resulting in an overheating problem

1990 Geo metro popped and poured white smoke out


its a GEO POPPER.
"no oil up on crank case"

no idea what that means.??????
yes PCV valve. do clog.

white smoke at end if tail pipe.
you didnt say where,?

white smoke has 2 reasons.(tail end)
Steam and oil.
steam goes away fast and looks just like moms tea pot. and smells sweet, like the antifreeze in engine. (rad cap off ,sniff sniff, cold engine)

oil burning, smoke is very very slow to go away.
and smells like , blush burned oil.
if not sure what burn oil looks like or smells like
take out the dip stick on a hot engine
let it drip to the hot exhaust manifold there.
now you know. and is a key diagnostic skill.


no oil seen on dip stick end?, you mean that?
well you need to keep that from happening,
doing weekly service, and for sure old cars.
26 years old.

low oil invites blowing up a good engine.
for sure.
if it did that smoke is oil
if it did 10x worse, both .

my wild guess is you meant to say
I didnt see oil leaking on top of engine.
right?

if the engine backwires to the air cleaner
you forgot to replace the cam belt every 60k miles
the pcv will also be clogged, on cars not getting proper service, super colon.
if the PCV clogs,engine may leak oil bad.

this engine btw is a G10 3 cylinder.
with TBI injection.
we can talk TBI all day, owned one.

white smoke can come from many places
exhaust manifold, leaks of oil can land there
engine can back fire to air cleaner making smoke.
tail end.
steam is much worse. ill not delve in to that yet/.

88 thunderbird white smoke and water coming from tail pipe


Possibly a blown head gasket, letting coolant into the cylinders to be burned. White smoke is usually coolant burning. Have the engine's compression tested to verify.

My 98 firebird tail pipe blows white smoke and water out the tail pipe then as i let it sit for 30 minutes the engine gets hotter then gas like smile and heavier smoke come out the tail pipe it also s


One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
