Passat (B5) :: Smoke Coming From Exhaust When Accelerating To Get On Highway
Sep 25, 2012
I have been searching online for days trying to find out why my car is smoking. i recently broke the oil pan on my 03 vw passat 1.8T. When I broke it I didn't know what had happened and I am sure all the oil drained completely out. The turn off engine now light came on and immediately shut car off! But I am not sure if i did in time before doing any major damage. my husband replaced the oil pan with a new one and everything seemed to be running good. i drove it for about 10 days and i noticed a whitish (I am not really sure of the color cause it was in my rear view mirror and couldn't see well) smoke coming from the exhaust as i was accelerating to get on the highway lasted about maybe 5sec then stopped. it has since done it 2 more times as i am getting on the highway but not every time. There are no fluid loss doesn't overheat when driving it all the fluids are good. I thought maybe head gasket or cracked head but husband says its not. the last it did it i stopped driving it in hopes to find out why its SMOKING!!!

I own a Lancer Evolution X and I've been having a strange issue where, when accelerating around 2500-3500 rpm a thick cloud of blueish smoke starts pouring from the exhaust for about a second or two accompanied by a loss in power. The smoke stops quickly and then it runs like normal. This only happens once in a while for a second or two. When idling there is no smoke. Or at Wot. There is no coolant mixing with oil. The oil was recently changed with the proper oil. and it still happens once in a while. I checked the turbo and there is no shaft play or oil inside of it. There is no loss of boost. Although I did see a tiny pool of oil near the turbo inlet and some more oil coating the inside of the intake pipe. is it possible that the turbo just sucks up some oil that collects at the end of the intake? the PCV line which connects to the intake appears to be letting some oil into the intake.

As the title states I have lots of blue smoke out the exhaust and the smell of burnt oil. Checking other posts it looks like it could be a diverter valve, a pcv valve or the Turbo. I checked on line and autozone and parts America say these are not required for my car. I checked my Hanes manual (yes, that's all I have) and they don't have the DV or the pcv listed.

My 2001.5 Passat traditionally does not start easily when it is less than 6degrees outside. Today it was that cold..it started easily..but about 30 minutes into my drive to work..I realized it was a little smoky and exhaustish smelling in the car..once I realized it wasn't the car next to me..i realized if I turned off the heat..the smell went away..but at the stoplight..i could see smoke coming from under the hood..out the corner by the passenger/dashboard... Car has 80,000, recent oil change, what it is?

1998 Passat 1.8T Sedan, Manual, 118k miles, new head at ~ 87k due to broken timing belt. (Changed oil approximately 1.5-2k miles ago, no loss of oil evident). No noticeable loss of power. No MIL and no DTCs in storage.
But there does seem to be a bit of exhaust (puff....puff.....puff...) that seems to be coming from under the turbo side of the engine, but it is hard to tell.
Recently - over the last couple of weeks - noticed at start-up in morning, significant amounts of blue smoke from exhaust - eventually subsides to nothing after a couple of minutes. BUT, it only seems to appear when the car is angled with its nose slightly up in the driveway and not with its nose down. Lack of it occurring with its nose down was only tried twice; I may need to check it again.
After reading many posts, I thought it might be:
1) Oil overfill at last change - I noticed that my oil was less than 1/16" above the top bend. I doubted that would be the problem, but I siphoned off the small bit and it is within or just below the bend now (hard to read). It might be the oil since I used the Valvoline full synthetic MaxLife that is VW approved for the first time, but I find that hard to believe since I have been using synthetic for a couple of years now.
2) Oil getting into the combustion chamber via oil in the turbo system. Checked the low spot in the hose just before the throttle body. Seemed virtually dry; that's not the problem.
3) I guess it could still be oil gathering some place due to the failure of the turbo, but power seems quite normal.
4) Problem potentially with the PCV (actually called the breather and bleeder valves) and/or vacuum system being plugged up. After reading all of the posts regarding that I am starting to think (HOPE) that is it and not the turbo. While I do understand that flapper valves that are stuck would create greater pressure which could result in oil being forced into the chamber past the valve seats, I am not sure why the angle of the car while parked would matter since the higher pressure would only be occurring while driving; and the blue smoke goes away after driving and doesn't appear until next morning. But perhaps I am missing something.
Particularly which valves I should check/clean if I am seeing this smoking exhaust at start-up, but only when the car is parked with the nose up?
5) Sticky valves at the back-side (cabin-side of the engine)?

I recently had a problem with my car jerking slightly on highway, and I think I've resolved this by replacing the spark plugs. It does still do it, but maybe only one or two jerks per 100 miles. It used to be one or two jerks every 30 seconds. So I think I've found at least part of the source of the jerk. I could possibly purchase new spark plug caps (wires) and hopefully that would put that problem to rest.

So my car has white smoke coming from the exhaust. On start up, on warm up, on hot idle, and on cold idle. The coolant in the reservoir is quite skanky looking and I've been meaning to flush it but haven't gotten around to it. But I've done quite a lot of research lately and also just have my own personal experience (employed as a mechanic at a small engines shop for quite some time.) and I've found the most common answer would be a head gasket problem, or even more serious, a cracked block, causing coolant in small amounts to leak into the cylinders. I figured that would be the answer I would find but I like to do some research before I go prodding at my car.
The exhaust is white, not grey, not blue, not black. A nice pure white color, and obviously comes out thicker and in larger amounts when you give it some gas. Also it smells sweet. Another clue it could be coolant.
Another thing that made me worry was when I replaced the old spark plugs, they looked like they were being run in a really lean engine. Barely any carbon tracks on them, almost clean looking. Which worries me. It could be suggesting that I COULD be burning water (coolant) in my engine. The coolant level in the reservoir does go down but at a pretty small amount.

My Elantra is at 14k miles and it has happened twice now that the pipe has released white/grayish smoke when accelerating abruptly (pretty much forcing the engine) on the highway above 60mph. I can see in my mirror that it leaves a pretty big smoke screen behind me.
I took it for an inspection after the first time it happened and the mechanic said it might have just been steam and that I should not worry about it. Since my 15k maintenance check is coming up, I will ask that they actually check on it.
I'm also curious to know if this could cause me to get a ticket? I'm thinking I could get pulled over for "imparing the vision of drivers behind me and making it dangerous for them", or something like that.

I recently purchased Sonata NF 2006, with L4 engine with 108 miles on it. I noticed that mpg is very low - 16-17 50/50 city and highway. The engine runs smooth and pretty fast for 4 cylinder engine, there is no smoke coming from the exhaust. While driving with A/C on i did not notice any pressure on generator or anything like that.

I just purchased an '06 V10 a couple weeks ago. Today, I was about 11miles into my 15mile commute when I noticed A LOT of white smoke coming out of the back. The only time I'd seen smoke like that before was just before my old Ford Explorer caught fire. I immediately pulled over and took a look. White smoke (maybe steam?) was billowing out of the exhaust.
I say steam, because it didn't have the strong diesel smell I would've expected. I decided I couldn't sit there parked by the highway, so I got back in the car, checked warning lights and pulled out. Within 1/2 mile, it was gone. Nothing. No more problems the rest of the way. What this might have been? I have 1100 miles on the vehicle and this is the first time it's happened.

When accelerating there is a noise that seems to come from the exhaust (can not be duplicated not in gear). This noise got louder recently, and then the noise stopped. When the noise stopped, the check engine light illuminated as well as the VCS and VCS off lights. Is there a common cause for this and/or trouble shooting steps that should be followed?

My 2011 Sonata is now at 56000 km (35k mi). While driving with a friend, I floored it when entering on the highway and he told me there was some dark smoke coming out of the exhaust.
I take very good care of my car and recently started using supreme gas and synthetic oil. It runs very smooth and never really had any problems... should I be worried? Is this normal?

Literally drove the car yesterday for three hours nothing was happening. Went to turn it on today when it idols a little constant white smoke comes out of the exhaust! Then when I'm driving and my turbo boost lets out a big cloud of smoke comes out. What could this be? Also just filled my car up with gas from empty today if that matters

It's a 2001 camry Solara .. When I start my car for the first time every day, I have white smoke come out my exhaust usually for about a minute or two but it runs fine after that. But it's like a cloud of white smoke. I checked my oil and it's fine. What it could be?

2009 Camry 4cyl
I changed my PCV valve over a month ago and still have white smoke coming form exhaust on startup. The smoke goes aways as always, after that the smell is gone and the car runs like normal. The smell of the smoke is not really sweet as if it was coolant leaking, but its not exactly smelling like burnt oil either (I've had cars that burnt oil real bad and it smelled different than this camry).
I've been keeping an eye out on my oil and coolant levels, both seem to be ok. I refilled my coolant tank to full about 2.5 months ago as it was very low and its still almost at full right now. My oil after about 4k miles on the dipstick measures right in the middle of the min and max dots, which it has been for as long as I've owned the car. So these levels are ok I think.
Now, I've read somewhere a while back that after changing the PCV valve or rather after taking the old one off that there still will be some residue to be burnt off. A way to get rid of that is to create a makeshift vacuum by plugging one end of the hose (the one that attaches to PCV valve) and leaving the PCV valve off while running the engine, putting some kind of cloth or similar over where the PCV valve should go to collect all the burnt stuff, thus cleaning the remainder out. Is it possible that this might be the a solution?

The exhaust from my caprice if thick and white. And there's a strong carbon smell. Could this mean my cat converter is bad?

On cold start or when the cars been cool down for a hour or so, a huge cloud of smoke will come out. it smells plastic burn than a rich gas smell.
So far this is what i did, a oil change, add a no smoke oil treatment, replaced with an oem pcv valve (this fix my rx300 smoking issue years ago)
Video 1, Friday at 3pm. the temperature is ~60 degrees, less smoke after a pcv changed
Video 2, Friday after noon at 6p.m. ~50 degrees
Video 3, Next day 10 a.m. ~48 degrees
In person it looks white smoke, but the camera captures it more blue smoke. I have been constantly monitoring my levels and oil and coolants are just normal.

I was driving yesterday going up a hill in lower gear... i think 3rd... and had the RPM's up sort of high, I heard a noise that sounded like if you stuck a stick into a fan...smoke also came out of the exhaust when pressing the gas.. smoke has come out before but I got my oil changed figured it might have just been burning off some oil.... I was thinking the catalytic converter??

1969 American Motors AMX....
I purchased a brand new motor and had it installed in my AMX w/ a 650 demon carb. This motor has as approximately 20-30 miles on it after engine was installed. Engine had some blue smoke coming primarily out of passenger side exhaust at first. The smoke was light to non-existent when car was started, and got progressively worse the longer the car was running - after driving for 3-5 minutes, the smoke would envelop the whole road.
Smoke also got worse as a few more miles were put on the engine. Engine started fine and idled fine - no problems when stopped at a light for a few minutes. Oil pressure fluctuated between maybe 35 psi to 90 psi while driving (to the best of my memory). Brought the engine in to be looked at. I've attached pictures - the ones in the engine were taken w/ a scope.
Found the following:
Oil extremely fouled and smells like gasoline.
8 spark plug gunked up and black
5 spark plug black (across from 8)
Ceramic burned of #5 header runner
No oil leaking past intake manifold gaskets
Fuel (and maybe oil?) on top of intake valve, and no carbon deposits
Fuel (and maybe oil?) on top of piston
Vertical scoring on top of cylinder wall
PCV valve connected to intake manifold, going directly to #5 and #8 - not sure if this is a problem or not.
What I'm trying to figure out, is this a problem with the motor, or a problem with the installation...
