Hi, Girlfriends Honda CRV with , miles runs great, idles great, shifts great and has plenty of power. Blowing out giant clouds of white smoke while hot or cold. Does not overheat or use any coolant. Is the engine toast. I have to get a smog check in California.
It could be residual oil in the exhaust system and it might take a few days of running to get them cleared. Drivers must understand the concept of smoke from cars. On the other hand, thicker smoke is a pretty big issue. No I didn't replace the valve seals Was this answer. Drivers can also see the water in the fuel or a leak in the head gasket.

When there is white smoke coming from the exhaust, it can mean a few things. But, a LOT of it can be a sign of big trouble. White smoke itself is not necessarily an indication that something is wrong. Here are some of the most common things that cause it broken down by smoke thickness. Keep in mind that some smoke is completely normal at times. When you fist start your vehicle espescially in colder climates white smoke is normal until the engine warms up. This white smoke is a natural part of the combustion process.
You know your CR-V. If something just feels off or different about it, take it in and have a mechanic look at it. A lot of white smoke typically indicates the following problems:. If your engine is running rough, and billowing out white smoke, it very well could be either a blown head gasket, or a cracked head.
As the engine coolant leaks into the oil system, the oil looses its ability to properly lubricate the engine. Eventually the engine will seize. The symptoms of a cracked head are similar to that of a blown head gasket. A compression check is often recommended when determining whether or not a head or head gasket is blown. A blown head gasket is nothing to ignore.
If you feel like there is anything that you would like to add, please leave a comment below. Good luck! Thin Smoke When you fist start your vehicle espescially in colder climates white smoke is normal until the engine warms up. Check the temperature gauge. If the engine is overheating currently, get it shut off as soon as safely possible. When the head gasket blows, it typically causes more than just white smoke. White smoke is often the most visible symptom of a blown head gasket.
Cracked Head or Engine Block The symptoms of a cracked head are similar to that of a blown head gasket.
Does not overheat or use any coolant. After that, we will come to the head gasket. In order to fix it, drivers have to remove the intake manifold and examine the intake gasket.

Another cause would be a broken piston, but you say it runs well. White smoke when the car is warmed up, not so much when first starting it in cold weather usually means coolant is getting into the combustion chamber.
O2 sensor s should be checked first. Hopefully one is broke and fixing it will resolve the problem although unlikely in my opinion. After that, the next possibility is the fuel pressure is off, or the MAF is broken or maybe it needs to be cleaned.
The seal in the master cylinder can leak brake fluid into the brake booster. The vacuum hose to the brake booster can then suck the brake fluid from the brake booster into the engine where it burns and causes a white smoke out of the exhaust. Is the smoke or steam coming out of the tailpipe or somewhere under the car? Are you losing coolant or any other fluid? What does the smoke smell like? How was this checked?
Hondas use alumasil engine blocks with no cylinder liners…The piston rings ride directly on the aluminum cylinder walls…This technology usually works well, but when it fails, massive oil burning results…If you are seeing a LOT of smoke, then ONE of the fluids motor oil, transmission fluid, coolant, brake fluid is being consumed at an abnormal rate.
What Tester described happened to me and a new master cylinder solved it different make of car. My older car had a vacuum modulator for trans shifting. Of course your newer honda does not use engine vacuum to control trans shifting. Burned trans fluid in intake. Synthetic oil is chemically the same as convention oil with impurities removed.
So hows it going to burn differently?? Flooring the motor prduced huge clouds of pure white smoke. And knocking…God, did that stuff preignite! Caddyman is right.
Back in the day, early Honda alumasil engines were failing prematurely and burning a lot of oil which got them failed during emission tests because of visible smoke…Their owners learned that if they switched to the heaviest grade of Mobil-1 synthetic oil, they could sometimes get past the test because this lubricant produces very little smoke when it burns…What smoke there was was white, not blue….
White Smoke From Exhaust: Main Causes and How to Fix
If you start up a vehicle with a gas engine and you notice white smoke blowing out of the exhaust pipe, there are a few reasons why this could be happening. One reason for white smoke is very common and completely harmless.
This is a common occurrence, especially in colder climates. When the warm or hot exhaust gases meet cold outside air, condensation and steam is a result. After a short amount of driving, the white smoke should lessen. If you continue to see white smoke coming out of the pipe after the engine has had a chance to warm up or while accelerating, then your coolant might be leaking internally. The most noticeable symptom of internal coolant leakage is when the white smoke is billowing out of the exhaust pipe and leaves a sweet odor in the air.
If you the white smoke consistently comes out and the sweet odor smell is present, then it is definitely a problem with your coolant leaking. The reason why coolant usually leaks is because there could be a crack in the cylinder head or even engine block.
Even if the crack is small, the internal coolant can easily leak out and contaminate the oil of your engine. This is how the exhaust smoke ends up turning white. The combination of the coolant and engine oil will create a milky appearance in the smoke. All it takes is for just a little bit of coolant to get into the combustion chamber for white smoke to be produced.
As a result, your engine will get worn out much faster and its internal components will get damaged. In this case, bad seals or piston rings cause oil to leak into combustion chamber which then mixes with fuel and burns. The result is a white or light bluish smoke that comes out from exhaust manifold. If you want to fix this white smoke problem , the easy solution is to take your vehicle to the nearest auto body shop as soon as you notice it.
But if you are trying to fix this yourself, never try to remove the coolant reservoir cap with the car still running because the engine will be too hot and it will cause you serious injury. Once the car has had a chance to cool down, check the reservoir and see what the coolant level is at. A faulty fuel injector , usually one that is stuck open or is leaking from the o-ring, will deliver too much fuel to the combustion chamber.
This excess fuel cannot properly burn in the engine and instead comes out as white or gray smoke out of your tailpipe. Replacing the bad injector or its o-ring is the solution. A diesel engine requires precision timing and fuel pressure of the injector pump. Thank you, the info was helpful. Is there any lubricant or anything else that can be mixed with fuel or engine oil or coolant to reduce the white smoke emission. If a coolant leak, no. So what could be problem when the smoke only come when you start the engine once driving there is no smoke.
Also it does not have a sweet smell at the exhaust it smells like gasoline could this be a fuel injection problem? Could it be because the person that put the radiator and just clip the copper part of the transmission cooler line. I recently had my car in for a major repair. I had also flagged to them that it was intermittently billowing white smoke. It appears they did not address the issue with the white smoke from the exhaust.
Could this just be a bad seal? I know for sure that they are going to awkward as they had real problems with this initial repair — I think they bit off more than they could chew and I suspect they have barely broken even on what was a very time consuming and expensive repair.
It does sound like intake valve seals to me. When idling, the vacuum pressure is higher and you are sucking in a bit of oil.
When you give it gas from a stop or when reversing , the oil gets in the combustion chamber and quickly burns off. My car blows out a large cloud of smoke when i start it for the first time everyday and then stops but the area around where my belts areunder the hood is making a clattering noise.
I recently just got a new radiator put in my 99 Jeep Cherokee as a new water pump also from overheating when I came back the next day to fix it because I was broke down at the store it would not fire up only with jump start and pumping the gas as soon as jumper cables were taking off car shut off now it will crank over but there is water or fluid coming out of the tailpipe and white smoke what could this be the person that put the radiator in cut the transmission cooler line could this be the reason.
So what could be problem when the smoke only come when you start the engine and AC on in idling time 4hour or more, and accelerator pressing white smoke coming. I did the heard and changed the valve stem seals, petrol pump plugs, oil filter and timing belt on a Mitsubishi lance glx 1.
After that there is a smoke coming out when I start the car and once the engine is warming it died down. What coup be the reason? You should notice less and less smoke until it final burns off completely. When I accelerate my car Mitsubishi Galant , often miss-fires and a puff of white smoke comes out…then she takes off.
I recently had the oil pan replaced and the guys told me my spark plugs, timing belt, and some pump need replacing too. Will this solve issue? Should I be worried? I have a ford mondeo 2. Every now and again about once every 3 weeks or so I have either smoke pouring from the engine for about 2 minutes if I am stationary or if I am moving the car coughs a little and I get plumes of white smoke from the exhaust for about 5 seconds then it all clears.
I have no other issues and dont lose any oil and it is serviced very regularly but the smell from the smoke in the engine is burning oil. My GMC Sierra has , miles.
If I park it say 3 hours it will smoke but less. Check your oil level. You probably have a small oil leak in the combustion chamber which burns off from the heat after starting the car. The longer the car sits, the more oil drips in there so you have more smoke. I just recently put a used motor in my SUV 04 Land Rover,due to the other one having a crack in the engine block.
The older engine was leaking coolant in the oil so bad that water would even flow out of the tail pipe, especially if you revved up the engine. Of course the oil was white where the coolant was mixing with it.
Now I have what seems to be a good motor put in it after about 8 months. It seems to run well and in checking the oil, there is no coolant mixing. However, when the engine gets warmed up, it does begin to blow out some white smoke. Depending on how it sits some times it is thicker or really thin. I drove it down the road and did not see any smoke. When I drove it back and turned around, it blew out some white smoke. I revved it up some and it seemed to thin out and at times seemed to almost stop smoking.
The motor runs smoothly during this whole time. It should slowly dissipate over time. Sometimes after I run my AC for awhile while idling around work or sitting somewhere I turn off the engine and when I come back shortly after and start up the engine a decent size puff of white smoke comes from the exhaust.
Also today after that happened a low coolant light came on and I went to check it out right away. Coolant looked fine and light was off when I started engine back up. Could this just be condensation build up or do I need to investigate more? Ok i have a dodge Durango and it has a different motor in it the size of the motor is v8 one size smaller of the 5.
