I have a 2003 F150 with a 4.6. Exhaust is pouring out white smoke with a sweet smell. I have replaced upper and lower intake gaskets. Compression test on all cylinders are at 145. Confused and don't know where to go from here.
View 1 RepliesWhile driving my 2011 Elantra a few minutes ago I just heard a moderate noise much like I had just driven over an empty pop can. Then white/ grey smoke started pouring out of my exhaust to the point I couldn't see the cars behind me. Just had 15000 mile maintenance about two weeks ago. My hubby has a lot of knowledge regarding older vehicles but says he's never seen anything like it before!

Bought the truck from used dealer with 168k miles on odometer. Drove it for two months and the radiator started filling with diesel. Had injector cups replaced. Had new o-rings on injectors and valve cover harness (both sides) at this time. While in shop they wanted to put injectors in truck but limited funds haulted that. Got the truck back and drove it for a while and noticed that when starting the truck it had a miss till it warmed up, but went away. This has been going on for over a year, but now has gotten much worse. Over the past year it has gone from slight miss to a full on dead cylinder that you have to make the truck pick up as you drive it. If you leave it sitting for more than roughly 10-12 hours you have to plug it up or it has trouble starting.
The final push from this ole girl was the other day. Left for work, normal hiccups and such from the truck. I pull up to a stop light and notice the truck is not sounding like its running correctly. No biggie it will smooth out, or so i think. I head towards work and the farther i get from home the worse it runs...
It wont pull its own weight, barely creeping at times. So i stop and check all my normals(oil mainly... just replaced hpop fittings and o-rings) and add fuel to it to get it over half tank. Start truck, still missing. Pull out on highway and dump foot to floor. It takes off only to fall on its face and start blowing white smoke out exhaust and die. It starts back but apparently I pissed it off cause from there it only got worse!!! It done that all the way to work, one time being so bad i had to stop and let traffic go by as the smoke cleared the roadway.
I get to work and check oil and it was way low. I add oil and drive it to lunch and it runs good, no hiccups misses or anything. Yay, problem solved!!! WRONG!!! Head home after sitting for a few hours and i pull out the parking lot and it falls flat of its face and goes into its dieing and such again. I limped it home and its sat in the yard ever since. Tried to start it today and after being plugged in for a couple hours it only sputters on a couple cylinders till it slowly dies. All Ive got for my troubles today has been two dead batteries...
This truck has always been underpowered as well. And gotten terrible fuel mileage (8-10 avg)... But it sure is pretty!
I'm losing coolant have, excessive white smoke coming from the exhaust, and rough idle. Doesn't over heat or even try to overheat. The oil fill cap looks brownish white. It drives fine other than extremely rough idle. I know how to check a blown head gasket with the combustion gas test.
From what I've read blown head gaskets on 4.6 fords are fairly uncommon but a blown intake gasket is fairly common. How can I tell the difference?
My DD just developed a head gasket leak. I've been noticing a coolant smell for a few days and today saw lots of white smoke from the tail pipe. I figured this is where my coolant was going and sure enough there is coolant coming from the driver's side head. I've ordered the gaskets and new bolts, but need the install.
I think mostly what I will need is the intake and head bolt torque and sequence. I will need to take a few days off work to get it done. Truck is a 2002 F150 with a 5.4L engine.
My 2003 F150, 5.4L has been having some rough idle/misfires issues both at idle and under load.
I have fixed one big vacuum leak, replaced the PCV valve, new sparkplugs, seafoam and heet in the gas, replaced fuel filter, tested the fuel injector resistance. Coolant levels have not changed. The truck burns about a quart of oil every 1000 miles or so. The white exhaust is heavier than condensation, but it comes and goes. The rough idling comes and goes as well, and it usually happens under load and the CEL flashes.
The codes I get are random cylinders, po303, po308, po171, po174 were the most recent but there have been other cylinders as well. I clear the codes after each attempt to fix it and they come back different.
I notice that there is a small exhaust leak that drips water just behind the engine, and when I shut down the truck a lot of water will pour out of an area just behind the cab on the passenger side as well as out of the bottom of the muffler (small hole, looks drilled).
Usually the rough idle occurs after filling up the tank, but from different stations so I do not think it would be watery gas. I use Heet every fill up as well. Also, there is a sulfur smell after the rough idling occurs (catalytic converter?).
Today I drove to dinner in my 2012 6.7 with no problems then on the way home my brother said he noticed my truck was white smoking quite a bit and he said there was a very strong exhaust smell coming from my truck ( he was in his car behind me) I ran a diagnostic test and what came up was code P0401 (I believe that's right). Need to figure out what is going on with my truck before I take it to the mechanics and get charged up. The truck still has DPFs in it just has a DPF back exhaust and has a AFE cold air intake running on a stock tune. However I do have the DPF deletes and EGR delete sitting in my garage just haven't gotten them on the truck yet.
View 2 Replies2000 Nissan Sentra with 105,000 miles. Runs great. All scheduled maintenance from the beginning. Grandma owned until I got a hold of it 2 years ago.
The beginning...
The car has had a slight exhaust-type smell for about a month. I thought it was either an exhaust leak or a small oil leak. I overlooked this as it was running great and I only drive to and from work at a total of 5 miles/day. I was going to be driving it about 20 miles so I figured I should just double check the oil.
Before my drive, I checked the oil and the dipstick said I had absolutely no oil. Backstory: I got my oil changed about 2 months ago and they broke the dipstick. They replaced it with a new one. I drove a few blocks to get oil. I purchased 2 quarts filled it up. I drove off and about a half a block later it started smoking bad. White smoke canvassing the whole street.
I turned around and went back to the auto parts store. I had a guy come out and look at it and he was baffled. The only thing he though was that it had run completely dry and it need more oil. We put 2 more quarts of oil in it (4 now) and it did not register at all on the dip-stick. A small oil leak was discovered coming from the head gasket (that was the smell). Also, there was no milkiness under the oil cap indicating
I decided to drive it back to work to leave it overnight. It smoked like hell and I made it about 4 blocks before it died. I pushed it the rest of the way and it stayed overnight.
The next day, I spoke to a mechanic friend. The only thing he could think of was that the dipstick was not the right size and it wasn’t reading any oil. The oil I put in was extra and the car was burning it off. He suggested I drain out all the oil and put 4 quarts in.
I drained all the oil but only 4 quarts came out. I added 3 quarts of oil and checked it again. Not it was reading about 10 times more oil than what I was supposed to have.
My mechanic friend said to start it up and the oil level should go down. I did start it up and the oil level did go down but it was reading about 5 times more oil than it should have. That is where I am at at this point. Hopefully it isn't a blown head gasket or piston.
My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.
View 7 RepliesI have a 2008 Ford 250 diesel that is pouring out white smoke from the exhaust when it goes into "cleaning filter" mode. I really don't understand this because I have a dpf delete with a sct tuner. I thought with the tuner and delete the truck wouldn't go into filter cleaning mode. I contacted Ford and they said it was normal for white smoke to come from the exhaust during this process. What's going on maybe tuner is bad?
View 5 RepliesI have a 2001 Lincoln Towncar (178,000 miles) with a heater core leak. I was on the highway and got some smoke out of the ac vents and ever since then I've smelled the sweet smell of coolant in the air coming from the AC. I haven't had any more smoke or vapor since the one time. I did my research and asked around and understand this to be the tell tale signs of a heater core leak and that it's one of those fun jobs that's going to be a high price tag at the shop because of the amount of labor (8-9 hours).
Since the dash has to come out, I thought it would be worth it to pay a little more and have a dealer do it since they'd be more accustomed to taking out and reinstalling that particular dash. So I describe the problem to the dealer over the phone and they want to diagnose it before giving me a quote on replacing the heater core. Why? No clue, I even asked the guy if there was any other possible way for coolant to get into the vents and he said not that he could think of.
Anyway, I took it into the dealer and low and behold they found a different coolant leak. It turns out for a while Ford used intake manifolds with a plastic part that is known to crack and leak coolant. The dealer wanted to replace the intake manifold and clear the condenser drain before we even got into for the heater core.
So here's where I get to my question. I ordered an intake manifold and replaced that myself, I still haven't addressed the heater core. The first puff of smoke and the coolant smell happened almost 5 months ago. I've been driving around with antifreeze in my trunk and my eye glued to the temp gauge and it has not budged at all. I started thinking if I could get through the winter months I'd just bypass the heater core and buy myself another 7-8 months where I don't need the heater and I could save up some cash to have a pro replace the heater core.
Now that the warmer weather is here, I'm left wondering--could the heater core really leak for 5 months without me ever having to add coolant and with the temp gauge never going above it's normal level?
I have an 02 jetta 1.8t just recently put oil in it and it's now pouring white smoke at idle and right around when I'm in 3rd. When parked and running it's puking oil and I have oil sprayed all in the engine bay. I have it sitting now and there's still a drip.
View 2 RepliesOccasionally I get blue smoke in the engine compartment with a sweet smell after a long drive. No malfunction lights, oil, brake, coolant, power steering fluids all are normal level. VW service doesn't have a clue, says just drive it until it breaks down. He also informed I should never use Tiptronic for braking since it could damage the transmission(we live in the mountains). What is it for anyway? We use Mobil 1 synthetic oil, and it is not overfilled. Car has 120k miles.

View 8 Replies2001 SD F-250 SuperCrew 4WD, 7.3L (completely stock), 114K miles, automatic
We took Dad's SD for a 600-mile trip yesterday and today. The oil had 2000 miles on it, and we checked it before we left. The oil level was half-way down the hatch-mark, so we had added a little over a quart of oil to top it off, and I think that we may have added a little too much. Last night, when we got to the hotel and got out of the truck while it idled, a lot of white smoke that smelled like burning oil (like when you spill oil on an exhaust manifold) was fogging out of the exhaust.
It did this for a minute or two, then cleared up. All day today, on the way home (300 miles), about every time that I let off of the throttle either going down the interstate or stopping at a red light or stop sign, white smoke would pour out of the exhaust briefly, then stop when accelerating or in the throttle going down the road. What is causing this? Would too much oil (a little over a quart too full) make it smoke like this? The truck runs strong, starts and idles good, and no 'check engine' lights came on the dash.
my 2002 7.3 with 370k just started to puff a small cloud of white smoke on start up. i realize this is normal during cold months but it is currently 102* in Texas. it will do it on the first start up of the day or if i start it immediately after shutting it off at full operating temps and when i do get a smell of the white cloud it has a oil smell but this only lasts while the cloud is dispersing all of that only lasts about 2-3 seconds no loss of power good boost pressure when driving no rough idle at all nothing acting any different other than the cloud and the quick smell of oil...
View 14 RepliesEarly 99 7.3. Runs ok has a slight miss at idle however every injector when unhooked makes a change. Has white and blue smoke From the exhaust. Has enough blow by to blow the oil cap off as your unscrewing it. My question is, I know engine restore is bad for these trucks but I can't afford to rebuild the engine. If I run the restore and then clean the IRP once the truck dies is this going to mess anything else up. Do you think it will by me a few months to save up for a rebuild

View 13 RepliesI've been chasing a problem all summer. Began with crappy batteries dying intermittently. I replaced the batteries, FICM, finally cleaned EGR valve and replaced ICP with pigtail. The problem is still persistent. Basically a rough idle, puff of whit smoke on cold startup, rough running at around 1500 rpms( driving at 50 mph). The ICP was soaked in oil so i was confident replacing it would finally cure my issues. It actually got worse with the rough idle turning to a surging idle and quite rumbly at 50 mph speed. I guess its time to look to injector issues but i thought id check if after replacing icp/ cleaning egr. I also have a slight exhaust leak at turbo out that i can see. The clamp is not seated properly. This after turbo connection to exhaust.
View 1 RepliesI know, sounds like blown head gasket. However oil looks fine, no coolant leaking and coolant looks fine. It also does not overheat (that I can see, it dies first). This all started a few weeks ago. I changed spark plugs, oil and undercoated the car with primer. I did get some paint on the radiator. I also put techron in the fuel tank and changed fuel filter. The car ran fine before, now here is what is happening step for step.
Car starts fine, idle is a bit rough (it was before too) but nothing drastic. I rev car at 2500 RPM until it is warm. The thermostat stays in the middle yet I begin to see a good amount of white smoke coming from the exhaust. If I take foot off the accelerator the car will shut off at this point. If the car is not warm yet, it won't shut off. When it does shut off, I cannot restart it even with gas pedal down. It just cranks and cranks. When I let it cool down it starts up fine and the same thing occurs. I cannot tell if the radiator fans are turning on as the car dies before they turn on (it's cool outside). The thermostat never indicates overheating.
The entire radiator is smoking white (not from cap) but I assume that is from my paint overspray burning off. Could this be getting sucked in and stalling the car out when the car warms up enough to start burning off the paint? Could I have painted something inappropriate? What could this be? I know a decent amount about cars.
If I let the car warm up just by idling it will run until it gets warm then it stalls and again, won't start until it cools. It seems to keep running if I keep RPMS up but right when I take foot off accelerator when warm it shuts off.
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.
