I only see it on start up, after it starts I don't see blue smoke or smell it could this be valve guide seals? If so are they hard to change? This truck has 168000 miles on it and has a 4.6 engine.
View 3 RepliesMy truck has been having this issue pretty much since I have had it, but it seems to be getting worse, or so I think.
When the truck is cold, it does not want to move very well. Like it's missing, and it does this until it gets warmer. Also, I have puffs of blue smoke come out the tailpipe when this occurs with it cold.
Injectors? Injector o-rings? Stiction?
FICM volts are good at 46.5v-48v when cranking.
I have a mysterious exhaust issue on my 1991 Montero. After the engine warms up and I have been stopped at a red light for a minute or so when I accelerate away from the light a cloud of blue (I assume oil) smoke puffs out of the exhaust pipe. If I sit in the vehicle with it idling for, say, 5 minutes then the cloud of blue smoke can last all the way down the block. Then it goes away. Spark plugs are all clean. PCV valve recently replaced. Mo warning lights. What can this be?
View 10 RepliesAfter tooling around town and a complete warm up cycle for the engine I encountered a problem. The situation is this.... Had to go around a slow poke....waited until traffic had cleared and nailed it. My truck belched out a boat-load of blue smoke from the tail pipe. Could not duplicate this on the return trip to the stealer (Dealer). Needles to say, I am worried about the health of the engine....(no codes popped, or anything else as I had a code reader hooked up) My truck did the blue cloud again with a rev up in park after a cool down but wouldn't do it again, but there was a strong smell of unburned fuel at the tail pipe.

Alright so In January had head gaskets done on my truck and when I got it back it Dont have any low end power and I noticed it was using oil. If I let it idle 15 min or so and rev it up it blows out a bunch of blue smoke and smells like oil bad. Been trying to figure out whats going on. Ive only put about 800 miles on it since I got it back for the head gaskets And its burned at least 3 quarts of oil. Its going to the shop on Monday gonna start with compression check and go from there I'm Thinking Its valve seals or a bent valve. But machine shop surface and pressured checked the heads. Truck only has 146000 miles on it shouldn't be having these lined of problem. Its an 03 5.4.....
View 7 Replies97 f150 4.2 ... Got a pickup awhile back and was smoking excessive mostly blue. Pulled the motor and had exhaust valve with hole in it and intake valve not seating on separate cylinders. All new gaskets and put back in truck. Deleted catalytic since they were both destroyed and cleaned muffler as best I could. Now it smokes but mostly white when revved up and maybe slight blue at idle. It's not using coolant or oil but went through five gallons of gas in short time.
Tests I have done : Checked fuel pressure and holds 38 psi all day. Tested maf o2 sensors, one is bad and tested vacuum and compression all good. It seems to be over fueling to the extreme. idles a little rough and will backfire on occasion. No check engine light but had all the o2 sensor issue codes. I'm leaning toward bad PCM... Would that cause the smoke rough idle and super rich condition??
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 1998 f150 4x4 with a 4.6 triton vin #w and only 150,000 miles but its smoking. On first start up everything is good to go but when the engine reaches operating temperatures it will smoke.
It does not smoke all the time, just on takeoff. Such as after taking off after sitting at a red light it will puff a cloud of smoke from both sides of the engine. The engine is smoking blue so I know its oil its burning.
I pulled the valve covers off last week and the engine is clean, no sludge or gum. Power is good, runs good, and has good compression. Why its smoking.
My truck is an 03 and I changed number 5 injector and number 4 injector, checked my ficm everything is good there now I have a contribution balance code for injector 4 now injector 5 and an EGR code some guys on hear before said it could be a sensor but today I talked to my mail man who also owns a 6.0 and he sounds pretty knowledgeable he says it's possible that it could be that the computer is not reading out right and those cylinders are getting to much fuel for an instant that's what's causing the sudden puffs of black smoke. My torque pro is giving me all these codes and I'm starting to think that there is something underlying....
View 10 RepliesGot a 2002 7.3 F-350 with 300,000 miles and for the last couple of years I've been getting blue smoke on cold morning start ups and its been gradually getting worse, it clears up after about 30 seconds and all is normal,No loss of performance, Oil consumption is minor, however I hate a vehicle that blue smokes, I'm guessing my issue is valve seals are worn, I was wondering if it is possible to replace the seals while the heads are on the engine? and was also wondering how much time it would take to fix? as i would have to have it professionally done. I know its hard to guess a time frame and everyone is different. Sounds like textbook valve seals to me but is there anything else I should check first?
View 14 RepliesI 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..........
View 5 RepliesI have 1998 F150 has 305,000 miles on it and its my everyday car runs over a 105 miles a day. I have no oil leak not even a drop however it does burn oil but does not smoke I say about 3 quarts a month. I have been thinking about changing the engine and keeping it as my everyday use . My question how many more miles can I get out of it or should I just wait until she breaks down or change out engine and trany now. Its has the winsdor 4.6 engine. Also I will be changing the transmission as I never change transmission fluid!!

View 5 RepliesExperiencing 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!!.
2010 F150 5.4L Engine blue smoke - YouTube
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.
So about a week and a half ago I went to crank my 03 6.0 truck up after having driven it to the mountains (about a 5hour round trip) several days ago. It was a little slower than usual but nothing too alarming, got to work and worked a full day, came back to my truck and it took even longer to crank. Drove to my girlfriends house to pick her up, only had it shut off for like 2 minutes hot and when I went to crank it it took two tries. From then on it was only bad at cranking when hot but now it takes 5-8 tries to crank whether it's hot or cold.
I took it to my buddy who owns a diesel mechanic shop and we hooked it up to his computer, everything checked out just fine, oil pressure was good, so was all injectors and ficm voltage, no red flags at all. So I went ahead and changed the icp, nothing, then he told me to change my aftermarket oil filter to motorcraft oil filter, still nothing, I also changed my oil filter drain valve and nothing.
When I'm attempting to crank the truck, after I hold the key attempting to crank it for maybe 8 seconds my oil pressure gauge jumps to normal. I have an ipr on the way to my house and I'm gonna try that as well. Also when the truck gets running it runs just as it ever has, no weird sputtering or stalling or cutting off. But when it does finally crank it puffs out a little black smoke.
I have a 04 f350 with 175k on it. At around 160k it had new head gaskets, 2-reman heads, egr delete, new oil cooler and it is studded and tuned with SCT and custom tunes.
Since after the head gasket change it seemed to have started blowing a little smoke on the cold starts mainly. In cold weather the starts seem to be harder or slower also. Now for the last 6k-8k miles there is a little smoke at a cold start. But if the motor is warm and it sits for a bit maybe 10 min or less it blows a nice puff of blue smoke or burnt oil.
The smell of burnt oil is mainly on hot starts not cold starts. It does not burn oil running. It will dump some black smoke under acceleration or load. Could this be an injector problem? Or something else? Can't figure it out.
My 04 6.0h started puffing bluish colored smoke typically only when I was accelerating. After a short amount of time I noticed it was smoking quite a bit when cold and until it had fully warmed up. I took it to the repair shop and they pulled it apart saying the turbo seal had failed and the turbo was full of oil. I purchased a new Garret PowerMax and had it put it in.
I picked up my truck and of course it was still smoking when cold. After it warmed up nothing, just like before. Since I just put a new turbo in I am worried this one will be ruined as well since the same condition exist. My mechanic said I need to run the truck for few days before the oil would get cleared out which had accumulated in the system. Am I mistaken in thinking that if it was residual oil burning that it would be more likely to do smoke when warm as opposed to when cold?
Since the turbo and seal have now been replaced what else should I look for to cure my blue smoke blues?
I have a 1994 Ford Ranger with 4.0 V6 Automatic. The problem is when it idles it idles low and surges up/down and pushes a very small amount of black smoke puffs and smells like gas. I have installed new coil, new wires, new plugs, new ect, new crankshaft position sensor, and new maf. It has new intake manifold, new injectors, new alternator and it still does the exact same thing. Nothing is phasing it. I ran the key on/engine off test and got egr codes and a map sensor code, then ran the engine running test and got 998 and 126 code. The 998 code says that its basically a hard fault/ have no idea.
I do know this is a donor engine out of another year not sure what year, but i know when i ordered the coolant temp sensor the only ones that would plug into it are the years 1990-1993. Now here's my other question, why would the computer give me a map sensor code when truck doesn't have a map sensor? It has MAF sensor, and why egr codes? The truck doesn't have egr and never came with it. I do know I've unhooked battery and replaced the maf and its like it doesn't even recognize it? Could it be the ecm/computer bad or needs flashed?
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?
View 24 RepliesOk, I have owned my truck for almost a year and it has 151,000 miles. I have noticed on a few occasions puffs of blue smoke and especially at night in the headlights behind me I notice a lot of smoke when I'm getting into the throttle hard. Under normal driving conditions I don't usually see anything.
Today I noticed it when I was backing my camper(8000lbs) up a small hill onto the side of my garage. It was puffing blue pretty good going up the hill while it was under load.
I have no check engine light on, the truck seems to be running fine. My oil consumption is about 2 quarts every 3-4000 miles. I tried the blow by test with the oil cap but besides some smoke out the filler neck no problems... I don't know very much about diesels so for me to try and trouble shoot this is a problem.
Some background, my truck has been sitting in the garage for a good month and I haven't started it. Been putting in 6 days a week for over 2 months at work, 60+ hour weeks. Today, I start the truck, it immediately dies. Successive attempts same result, blue smoke out the exhaust. I kept it running by revving it up but then it dies again. It's the original battery, 5+ years old now. MM shows 12v at rest, drops while cranking. I put the charger on the battery for a bit while I came inside to ask this, it's on trickle 2A and its at a 7 on the dial, and it goes to zero when fully charged.
I've been thinking I'll need to replace the battery before winter, but I'm hoping it's just that since its discharged that's why it won't stay running? Any thoughts? I have had zero issues with this truck but having a company truck over a year now, it sees very limited action. 2010 5.4 with just a tick over 40K, oil is good, air filter is clean and free of obstructions. We do live in the woods and have critters that hang out in the garage, like squirrels and chipmunks but I'm not seeing any evidence of chewed wires that I can see. It's in the garage and using a droplight I don't see anything obvious. Maybe it's as simple as I have to take the work truck and get a new battery I hope...
