Sonata NF (2006-10) :: 2007 - Valve Ping / Blue Smoke Out Of Exhaust At Startup
Dec 11, 2010
I have an 07 Sonata V6 Limited with 65K miles. Recently I've noticed at startup, the valves pinging and blue smoke coming from the tail pipes. Settles down after a few seconds and doesn't do it again if you shut it down and re-start. Last time I experienced this was on a Silverado with well over 100K miles. Back then it was valve seals. Could this be possible with 65K? I noticed in the maintenance log that they request having valve clearance inspected at 60K. Could this be causing my condition? I'm the second owner, so the 100K warranty is out of the question.

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?

Sonata 2007 3.3L V6 ... I have nearly 70K on my Hyundai, and I am the original owner. Everything was fine until 24 hours ago until I got a knocking noise. I stopped, shut off the engine, and had it towed.
The mechanic says that based on the symptoms (knocking, some white smoke from exhaust) that it is powertrain warranty related, and I should be covered.

How steamy the exhaust is right after a cold start? I have always noticed it in my passenger mirror, but yesterday I decided to stand behind the car and watch it right after starting it up, and I actually saw a few puffs of black smoke coming out with the steam. I'm not losing any coolant, so I think all of this must be caused by the engine running extremely rich when cold, the fumes were pretty bad too. Once the idle settles down the black puffs go away, but the steam lasts a good while. I have never had a newer car run so rich that it caused black sooty smoke.

My 06' Camry has 141k on it and when I start it up in the morning it smokes and I have been told it is the valve stem seals, and since I'm pretty handy with a wrench. I was wondering all the tools and steps there are to replacing them and if you actually have to take the head off or not?

Most had said theirs did it intermittently and got better after awhile... Mine does it every single time. I start the car. Usually after sitting for the day at work or overnight at home... Not sure which direction to go with this (or rather my hubby) to go. What would be checked first? turbo, fuel injectors, and valve seals...

My car burns oil on startup. Mostly when cold. However the attached vid was taken today when the car was warm. Does not burn oil any other time. It is definitely not water vapor - smoke is blue.
Dealership replaced pcv after inspecting the turbo and all was good. Now they aren't sure what it could be.
My research tells me valve guides/seals leaking oil into the head. I don't show any oil loss on the stick so it's not leaking a lot of oil, just enough to create a little big of smoke.
Question - is this a big deal? Do you occasionally see smoke on startup? I'm trying to figure out if I should press the issue with vw or just live with it - I really don't care about the smoke but don't want long term reliability or resale issues.

two days ago i noticed First start in the morning the truck billows out blue smoke. In mean is enough that looks like an old 2 stroke dirt bike. Quite alarming. I've had HHS in for 4300 miles or so. I hope I did not mess the engine up by towing With the HHS in there. The injectors have been getting loud an indication that i need to change the oil again. The truck always gets louder when nearing oil change time. It reminds me of an old chevy with bad valve seals. Would turbo seals just go. The smoke goes away after driving maybe 2 min well i can't see it while driving. Truck runs smooth doesn't stutter or miss. It has been acting like the stiction is happening upon first starting after sitting for 6+ hours.

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 own a 2001 Passat, engine code AVF, the problem is that I have blue smoke on the exhaust, lots of it. The turbocharger has been tested and has almost no play in the rotor, but I have tried to blow some air into the oil intake and the air flow is very low, I have to blow quite hard so some air can go through. I also get allot of smoke and oil from the Crankcase Ventilation Filter and also I could see some oil around the dipstick pipe.
Now I don't know if there is a turbocharger oil return pipe problem (maybe it is clogged), the turbocharger itself or maybe some other problem.

I have a 2002 2.4L Camry with 120K miles. I plan to keep it for another 10 years so want to get it in better shape. All I've done so far is air filters and changing the oil. I did let oil changes go way too long a few times then at 70K miles started emitting blue smoke only at startup after sitting overnight. It looks like valve stem seals so the engine uses oil now but it's tolerable and I really need to avoid spending big bucks unless there's a breakdown.
I've read about a procedure to replace the valve stem seals without removing the head using compressed air, but am a bit scared to try it for fear I will get in over my head.
I'm planning on getting up to date on all recommended inspections, changing spark plugs, coolant, air filter and cabin filter and plan on changing the oil from conventional over to 10w30 synthetic w/ subsequent 5,000 mile intervals from now on. I'm in a better financial situation now so can afford parts but want to try to do all labor myself unless a mechanic is necessary for something extremely important or critical.

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.

Since new, I've noticed that my truck makes a ticking/pinging/tiny backfires when cold. I can't really hear it unless I open my window(s) as it comes out the back end and isn't anything in the front end (...its an exhaust issue). Is the truck just running rich when cold?

I was watching my wife drive off yesterday, and noticed a puff of blue smoke (oil) from the exhaust when she started moving.
This is a 2000 V6 passat. The car has a valve clatter when you first put a load on the engine that goes away quickly. I've read that this is likely the cam tensioners leaking down - is that right.

05, 170k miles. Studded and egr delete but I don't have paperwork on either. Got a pretty good deal on the truck but I have a few questions..
It runs and starts great, warm and cold, with only a little blue smoke on cold startup. but every now and then when idling (say at a stoplight) the engine gets noticeably rougher, not terrible. No smoke. Goes away after 5-10 seconds.
When I remove the oil cap, there is a "puffing" blow by, not constant, and its not enough to blow the cap off if I set it on backwards. Just puffing.
This may be related, but I pulled the starter wire off the drivers side and touched it to the battery to hear how it cranks, and there is a noticeable blip in the cranking, its not 100% smooth.
Don't think I am losing any coolant. Runs great, getting 15MPG. No CEL. I went and had a relative comp. check done, cylinder 7 is the problem. We both are leaning toward there being a valve problem So I pulled the valve cover, now I have a few questions.
1. When I crank the engine over without starting, I can hear a "pfft....pfft....pfft" chug of air every revolution. I pulled the cover to see if I had a obvious rocker problem, but can't see anything because the oil rail is in the way. I'm guessing this air puff is sign of a valve problem?
2. When the truck is running, there is a small, steady stream of oil running down the rail and dripping onto the valve cover mating surface of the head, I think it was at every injector, definitely 2 of them. Was getting dark, so hard to see. Is this normal, or do I have a leak? Truck has updated dummy plugs.
My next step is probably going to be pull the rail, see if there is a obvious problem, then pull the head. And tips for me? Planning on having the HVAC evacuated then pulling the airbox.

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.

I have a 00 dodge caravan. Has always been a good van. Recently when I start it up first thing in the morning there is a puff of blue smoke come out of the exhaust. This will not show up again if you start the van up wth in an hour or so. If you leave it for 3 or more hours you will get a puff of blue smoke but not as much as the one after it has sat all night. What this might be????

Only had happened a few times in the last month. I start the car and it idles okay. drive down the road and then come to s stop and there's some blue smoke. It smells like burning oil. it only has happens 2 times in the last 2 months. only when its really cold it has happend. If I rev it when its happening I can see a big plume of bluish smoke and it smells like burning oil. after i drive after that no more smoke.
car has 95k on it
never been chipped
car has full turbo back and intake
car does not burn any oil between oil changes. oil stays at the same level.
did break an oil pan about 4 months ago. when I replaced it no signs on sludge.
turbo boosts fine
Car has had a rough idle for a long time. only when its a cold start and only last about 20 seconds. When I boost it or redline the car which is very rare no smoke at all. I have always kept the oil more on the high side of full. I usually fill it right to the high mark on the dip stick.

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...

2004 f350 4x4 sc dually 130K mi. Cranked truck this morning @ 18*F. Truck not plugged in but regular quick smooth startup. Noticed light blue smoke with normal condensation exhaust for about 5 seconds, then normal condensation exhaust for about 30 seconds. Drove truck at normal operating temps with 5* deltas. To my knowledge, truck has original turbo (Garrett), never been removed or cleaned by me. VGT at startup 70-72, running after warmup mid 50's. Is this a symptom of needing to replace turbo seal, and thorough cleaning while off?
