Lexus GX 2010+ :: Blue Smoke Coming Out Tailpipe Upon Start Up
Jan 19, 2015
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.

My RX350 has less than 18K miles and it has signs of bad valve seals. If I start the vehicle after it sits for a while, a large puff of blue smoke emits from the tail pipe. My 02 Dodge with 188K miles doesn't even do this.

I purchased my 2013 Ford F150 3.5L Ecoboost screw in December 28th 2013. I now have 12,000 miles on my truck. My transmission occasionally clunks in and out of gear. Mostly in stop and go rush hour traffic around 20mph. Dealer applied a PCM/TCM software update in July. Still clunks... possible 'slip bump fix' required?
When I 'punch it', I see what looks like blue smoke blowing out of the tailpipe. Tailpipe has soot buildup. I've also noticed a slight drop in MPG. I have NOT noticed a loss of power. Wondering if my truck needs induction cleaning?

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)?

Experiencing blue smoke shooting out the tail pipe of your newer F150. Mine has been puffing blue since 12,000kms, still doing it at 55,000kms. Been to 2 Ford dealers (6+X) and they can never seem to repeat it. However it has been getting worse. Shop foreman guessed and said its valve seals.
I took a video, which I will post here, contacted Ford customer relations, and they tell me until it smokes at the dealer they cant go ahead with any repairs.I told Ford my truck will sit on the dealer lot until it smokes again and I am not driving it anymore. Photo is worth a thousand words, video is worth none. This is driving me up the wall!!.

Note the blue puff in the video is my truck, taken last Friday, and this is a small amount. Normally it fills my driveway and garage.

Every 2-3 days, intermittently-there is white smoke coming from the tailpipe of my car. The car seems to be sputtering, like it wants to cough, plus there is vibration in the steering wheel. All this happens while the car is idle like at a light. Then on other occassion, I am driving on the freeway and the car seems to sputter even at 45-65 mph, then it just smooths out. No problem.
Today, I was in the parking lot, there was no smoke but some sputtering when I shifted from park to drive. I drive 30-40 minutes to get to work and very afraid my car is going to breakdown. Also, I took my car to Toyota dealership and was told they could not tell me what was wrong with my car and to bring it back when to problem occurs again. I have pretty much "babied" my car, so I guess my car is beginning to reach middle age.

I got my 2.0 turbo project up and running. no CEL but i did have a bad o2 code but it was erased and didn't come back.
Not only is it rough idle and smoking out the exhaust but i am also getting smoke out of my catch can vent.
The smoke looks black coming out of the tailpipe but little blue after it gets out a ways from the car. Where to look??
I did just replace a piston and install a head gasket spacer. I don't know if that could be causing it some and it will go away with some driving or what?
I have not taken it out on the road as I have some brake work to finish. so mostly it idled.
Here is a link to a video on what the car is doing : [URL] .....
Its a 01 engine code....

2001 F250 5.4 with 160K miles. My wife "borrowed" my truck as she drove away, I saw white smoke coming out of the tailpipe. The kind you see in cold weather. Its was 75 degree in Texas this morning, so what could that be? There is antifreeze in the reservoir and I recently changed the oil and there was no water in it.

I have an 04 F250, stock. Two times within the last week I have noticed whiteish smoke coming out of the tailpipe and a diesel smell. Could this be the glow plugs going out and not burning the fuel, I have not changed them since owning the truck or something else.

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 have a 2005 Toyota Camry LE 4 cylinder, and I have been trying to figure out a hard cold start issue that also causes whitish grayish smoke to come out of the tailpipe when I first start the car.
When I first start the car after it has sitting at least 8-10+ hours the engine will crank over and being starting up but its almost as if it hesitates and then fully starts up. Once it does start the smoke will come out of the tailpipe for about 10 - 30 seconds and smells somewhat of burning fuel. I think the problem may be a leaking fuel injector. When I use my car during the day this issue doesn't happen at all after first startup
Coolant level and color : Normal no changes
Oil Color and level : Normal no changes
Tune Up: Done about 2 months ago
I uploaded a video to youtube of the car starting up here [URL] ....

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.

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...

Ok I thought I remembered reading about this in the past. This morning I detailed the V8 T (19K miles) and started it to back it out of the garage. Got a big puff of blue/white smoke out the back. I searched but found nothing. Should I finally run to the nearest BMW dealer for an X5?

I have a 2010 lancer evolution, intermittently under light to no acceleration the car emits a large cloud of blue-grey smoke from the exhaust accompanied by noticeable oil consumption. This only happens when in 5th or 6th gear or when it changes from 5th to 6th. It only seems to happen when accelerating onto the highway or when going up an incline in a high gear. It only ever lets out smoke when under 2500rpm, never above 2500 and only for a second or two. if I downshift to 5th while this is happening, it stops. I'm at a loss as to why its burning oil.

I have a 07 camry 4 cylinder with about 80k miles on it. Now on cold starts i started to notice that it will have a puff of blue smoke out the exhaust then it will go away right away and when i drive it there is no smoke and the car drives fine.
I did some research and Im thinking that it is the valve seals. Now my question has tried to sea foam it and then run thicker oil to see it it will stop the smoking? or will i just have to replace the valve seals?

02 camry, 128 K miles, 4cyl.
Since I started using castrol titanium full syn oil, I have noticed increased blue smoke on initial start up, usually after overnight.
Time for another oil change, what OIL to go with? I was thinking back to Valvoline maxlife dino oil.

In have a 2005 Toyota Camry with 120,000 miles. Upon starting the engine there is a puff of blue smoke with smell of oil burning. There does not appear to be any smoke during the running of the car. What the root cause could be? Rings? Head gasket?

I have a 2003 Solara 4cyl, some months ago it started to blow light blue smoke on start, but would go away after a few minutes. My mech, could be the valve guides. Then about a month ago it blew a head gasket, didn't overheat though, as I stopped, added water and went to the mech. So new gasket and a valve job, but it still blows smoke on start. THe mech said going to 20w50 might work, it didn't. I check the oil last week, thought it should a couple of qts low, so I added oil, but the blue smoke is still there, and I started to smell oil burning. I thought maybe I added too much, so I add another oil change w/20w50....still have the oil burning, blue smoke on start... The mech thinks might be leaking in the rings...ugh....probably could/ve bought a new engine by now...... The check engine light had been intermittent, the mech said it the catalytic converter....it finally went off by itself four days ago....maybe it burned out..........
