Lexus RX 2004-09 :: Cloud Of Smoke Coming Out Of Exhaust On Cold Start
Oct 3, 2015
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.

This S10 has 4 wheel drive and the V6 engine and has 88,000 miles on it. Just about everything except the engine has been replaced because it was a work and plow car and took a beating. It is a great plow car, by the way. Recently a cloud of smoke comes out of the exhaust when you start the engine that has been sitting overnight. Mechanic says it is just old, but someone said that replacing the umbrella seals might do the trick. Stopped at my local auto parts store and they had never heard of umbrella seals.

So I'm trying to figure out the issue with my girls car, upon cold start sometimes a cloud of white smoke will come out of the tail pipe but not all the times, sometimes the oil level slowly drops but again not all the time, coolant doesn't look mixed but I'm not 100% sure. The car is the pzev 2.0.

As I was driving today on the highway, I saw a whitish cloud of smoke come out of the exhaust.......the car seem a bit wobbly after that. It only happened once. the ring around exhaust tip is all black. I am not sure if it has damaged anything? What it could be?

Ok, here's the situation... (Elantra GLS - Automatic)
I was at a 4-way stop sign. No other cars were around so I accelerated. Then suddenly, I hear and see a car coming at me REALLY fast, and well, I panicked. I floored the throttle (almost literally), and I heard something popping or maybe it was a farting sound... It happened so fast that I don't remember clearly...
Then behind me was a HUGE cloud of smoke behind me. I mean really, it covered up the whole street. It was 10 PM, so I couldn't really tell what color it was, but it seemed to be white... So I turned off my car. Checked the engine, no smoke from the engine. I started it up again, and instead to revving to about 2000 rpm at start up like it always does, it only went to about 1000, and more smoke was flushed out the exhaust.
I was close to home, and with no 24-hour mechanic shop around me, I drove home. As I drove home, I had quite a bit of smoke trail behind me which scared me through out the whole 2 minutes of driving. I got home, and I checked the exhaust again, but there was no more smoke. However, a burning smell lingered around the exhaust.

I was driving down a 2 lane road doing the speed limit and I found myself behind a car going much slower than the limit. It is one of those roads where every once in awhile the double yellow line is dotted so you can pass.
I finally got to the point where I could pass as there was no oncoming traffic, so I turned left to pass the guy, floored it, the tranny started to kick down into passing gear and then the car sputtered, didn't accelerate and blew out a huge white cloud from the exhaust and the cel light flashed on and off. The cloud was something like you would see in a James Bond film to get rid of cars following you. All of the cars behind me had to stop or slow up because you couldn't see. I didn't realize that until I looked in the rear view mirror. I thought the car just sputtered, I didn't even realize about the cloud until I looked back.

I have a 2002 Toyota Highlander 6 cyl, 148,000 miles. I get a cloud of white smoke from the tailpipe upon starting a cold engine. Smokes for about 1-2 minutes, then smoke stops.

At cold start (car sitting at least 8 hours), and the first block or so of driving, I have been getting smoke from the exhaust. I am not 100% certain whether to describe it as black or blue. If I start and idle the car, the smoke continues until I start driving.
After warming the car up, I have tried letting the car sit and idle for an extended period (over 5 minutes), and the smoke does not reappear.
Background;
- APR Stage 3 car, 17,700 miles
- On a particularly cold night this winter, the BFI clean catch did freeze up, and the car started blowing smoke. I removed it for winter and re-installed recently.
- Oil change with Rotella T6 and Mann filter 700 miles ago; the level when warm is at Max level
During the winter, it is hard to say whether this issue was happening. I noticed the issue some time after changing the oil, so I am wondering if the oil level may be slightly high. I changed the oil around the time the weather started consistently staying above 40F, though, so it could be coincidence.
I tried to come up with what the cause could be. What I was thinking (in order of easy to difficult);
- It's normal! The weather is warm, and the fuel trims have not adjusted yet, so it's running rich at start-up.
- It's normal! Typical 2.0T stuff.
- It's a catch can problem. Troubleshoot by removing it and seeing if the smoking stops.
---> Catch can is NOT full. I check it at least once per week.
- It's a turbo problem. The catch can freezing overpressurized the turbo lines and blew a seal
---> Although my experience has been that idling the car should bring the smoke back in this case, which I haven't gotten it to do.
- It's an engine problem.

Recently purchased a used 2003 Toyota Camry LE. After a recent oil change at the local Toyota dealer we noticed that when we start the car in the morning a puff of white smoke spews out from the exhaust for a few seconds and stops. There is no more white smoke while driving the car around. The car runs perfect and has no power loss. Initially we had noticed it was losing coolant. All the discussion on the internet pointed to a bad head gasket. We had a mechanic look at it and it turned out that the radiator was leaking and hence the loss of coolant. He also noticed the oil was overfilled so he brought it down to the normal level. The mechanic also checked the head gasket and claimed there were no issues with it. Replacing the radiator took care of the coolant loss but the white smoke still comes out only the first time the car is started.

99 1500 2wd 5.7 burb
Out of the blue I started old red up yesterday (after charging the dead battery) and got a huge cloud of white smoke. Smells of coolant so Im thinking oh great a head gasket. The thing is, I can see no trace of coolant in oil or vice versa. I started it up with radiator cap off, while cranking I got a little fluid spit out the neck but once it started it was not gushing or bubbling at all.

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?

I have a Ford Ranger 4wd, 2000 120k. Ran well, great shape, reliable and quiet running. Oil pan leaked and I got tired of going under and used Devcon in attempts to stop leak..reoccurring issue. So I get new 0il pan. Started it up following morning after driving errands and home from shop and saw a cloud of smoke on start up never seen before, cleared away and didn't think about it again. Drive round trip for about 70 miles and while driving at slow speeds back in town, the oil gauge started pinging back and forth, and the knocking started. By the time I got home I do not dare to drive it anywhere as while the oil gauge does not fluctuate anymore the rapping has increased. What could have started this chain of events? Can I expect the garage to replace the engine? Vehicle is worth 4k replacing engine probably 3K..while a beautiful useful truck body sits in yard is it really worth it? Bad draw on the cards?

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 have a 2003 Superduty with 193k miles that is bone stock. I sold the truck to a friend and when he decided to not pay the remaining balance on the truck, I took back ownership. The truck was having heating issues and it set at a mechanic shop for nearly 2 years waiting for a diagnosis on the heating issue. Fast forward to the present and I now have the truck at my home. Heating issue was the radiator but this is no longer a concern. When I went to pick up the truck from the mechanic, the truck started fine. Every other day for the last 4-5 weeks I would start the truck with no problems.
I get the truck tagged and start driving it on a daily basis. I've put several hundred miles on it but the more I drive it, the less it wants to start. Now it's to a point where it only cranks but won't start. I can take a gas rag and hold it in the intake and eventually it will start. Once it's running, it runs great and has no issues starting. But once it sets for 3-4 hours, it won't start without some sort of assistance.
While trying to find the issue, I've found and repaired 2 fuel leaks and in the process I replaced fuel filter, air filter, replaced glow plug relay, replaced batteries, replaced CPS. Fuel pump is working fine. I've tried the ICP test and doesn't make a difference.
The glow plug light or WTS light works so don't think its the GP. The CES light was on. Had it scanned and it was the air bag sensor so no support from the CES.
While I was working on it yesterday and after cranking on it for 5-10 minutes, it would act like it was going to start and black smoke would be coming out from the exhaust. I let it set to cool the starter it fired up like it had no issues.

I have noticed 3 times so far blue smoke coming out the tailpipe upon start up. I have not been able to reproduce the issue on demand but I have seen it myself 3 times and it concerns me a bit. It's a 2012 with 36k on it. I changed the oil at 1k, 5k, 10k, 20k & 30k. Last oil change was done by the dealer but every oil change was done with Lexus Filter and synthetic oil. I have not noticed a loss of oil by the dipstick either. I noticed the poof of smoke last week when I was outside at the carwash and one of the employees moved it. I also noticed it when I used remote start the other 2 times. It's not enough that I would be able to see it from inside the truck. I also have black carbon / soot build up in the bottom of my tailpipe but I think that's with all vehicles. I know if I bring it to Lexus they will say "Unable to duplicate issue" and send me on my way.

So I finally went and put the exhaust I had been wanting on my truck. Pretty simple set-up. I had the factory muffler cut off and a flowmaster 40 series on it previously. I liked the sound under load and at cold start but normal driving I could not tell a difference from a factory muffler. So I had the flowmaster removed. I still have 4 cats so it's not crazy but it is loud. The only time I have cackle is on initial start-up not even at WOT which was a pleasant surprise. I just like the look of a single exhaust but still want some sound. I have been gone awhile as I needed a little break from starting and also being drawn in to arguments.

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.

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.
