The newer engines are very critical to torque specs. If they were not torqued properly, even the slightest, you can have what is occurring. The older vehicles had much higher torque settings and this was hardly ever a problem.

SOURCE: 1993 TOYOTA TERCEL 1500cc Valve Seals Replaced now smokes much worse

You either have had the wrong valve seals installed, they are physically missing, or the valves are incorrect (too loose in the guides/stem too thin). The rocker arm seals will not contribute to your issue. If it did not have the oil smoke before you took the head off, the issue is with whatever the machine shop did. Valve seals have to fit TIGHT, or oil will go down the valve stem into the intake.
Take the head back to the machine shop & tell them to fix it. For free.

SOURCE: 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!!!!

Did you put Valve seals in the head???
Other than that the PCV is a good start...
But it sounds like the oil rings on the pistons to me.

SOURCE: mazda mx5 smoking problem

Please provide more details for analysis like:
- what is the mileage on your car?
- is it smoking continously or only intermittently? How much smoke is it?
- what colour is the smoke? bluish or sooty?
- does it smoke when engine is cold or hot?
- is your car losing power?
- is your car consuming motor oil and at what rate?
- has the engine ever been overheated?
- is there an engine MIL ( malfunction indicator light ) code flashing on your dash? If it has, then you need to get the workshop to run a scan of the engine's computer to find out what the possible faults are.
- by the way, is your mx-5 fitted with a rotary engine or the common 4-stroke piston engine?

SOURCE: I have white smoke coming from the tail pipe

hi... it all depends on the colour of the smoke... usualy blueish smoke will mean it is oil burning and your piston rings may be getting worn if it is black then it might be running too rich etc.. a little bit of water is fine infact usualy it is a good sign that your engine is not running rich or lean so it is pointing towards oil seals... also if it was running rich it would probably do it more when it was cold

Yes, sounds like bad head gasket or worse. Your trip to the store warmed things up and as the car sat, water under pressure worked its way into combution chamber. You could do coolant pressure leak down test, but hate to say you got big troubles.

Geo metro troubleshooting


First stepwould typically be to replace the PCV valve. It's located behind the valve cover at the bottom of the rubber tube that connects to the back of the valve cover and branches off to the air filter housing.

Alternate possibility:

If the head gasket has been replaced, it's likely one of the oil returns is blocked (replacement head gaskets, for whatever reason, don't usually align with the head correctly). The solution is to open the secondary oil return. I used a one foot piece of 4 gauge bare copper wire (more of a 1/4" copper rod). Remove the valve cover. Taper the end of the copper wire to a blunt point and drive it about 6 inches down the oil return on the backside of the head near the rear of the head (directly behind where the oil filler cap was).

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/.

My harley smokes


all engines do cold. its water vapor and or the hot exhaust, causing the air, to change dew point, (looks like steam)
on the white smoke smells like burned oil , it is, and is slow to dissipate like steam, (see moms tea pot , and steam fast dissipation?)

if it is oil , its most likely bad valve guides and seals, or both.
if a compression leak down test passes, its not rings, (mostly)

Just started to noticed white smoke coming out of exaust pipe. Noticed smell of gas. Is this normal for a car this old


Looks like you have a blown head-gasket. The white smoke is actually your engine coolant mixing with your engine oil and being expelled as a water vapor. You need to take it into a repair shop Immediately.

Wite smok from exaust system. When starting some time wite smok and smell of burning oil. Some time do not smoking.Do not pick up from low speed fast. The engine is turbo and inter cooler


Smoke can be from rings worn out, cracked piston, valve guide seals if smokes at start up then stops, fueling issues if fuel is to rich but that smoke is usually black, also if head gasket is blown or head is cracked water burning turns into steam which looks like white smoke. This can also be why won't start just turns over.

if theres smoke coming out of the exaust then the motor is smoking. sounds like you have a blown head gasket and it's low on water is why the heat isn't working.

Alot of white smoke is coming out the exaust pipe


Ouch!
White smoke means water (steam) in the engine cylinders, coming from the cooling system....
broken head gasket or cracked cylinder wall.

1998 - you might want to temporarily use an engine sealer. AutoZone can advise which is best for plugging a head gasket leak.
It will need to be replaced ($200+) and get valve job done ($100) at an ato parts store that has a machine shop, since the valve head must be removed to replace the gasket between thr head and the engine block.

Not likely, but it could be water in your gas tank. Did you just fill up?
or was the car driven with an over-heated engine?

Look at the opil dipstick. There will be a milky substance in the oil. That's water mixed with oil.

Sounds like it's time for a compression check. The head or gasket could be blown, and this test will confirm or deny this fact. Your smoke/steam and the oily residue are pretty good clues...accordianman
