Ford F-150 - 1997-2003 :: Excessive White Smoke Coming From Exhaust And Rough Idle
May 3, 2015
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?

I'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.

I have a 98 expedition with the 4.6l 4x4 and it has 158,000 on the dash had a new engine installed at 100,000 it started running rough and sluggish last week so I changed out the spark plugs and while changing the plug I notice oil on the threads of the two rear passenger side plugs. After the new plugs it was smoking pretty bad blueish white smoke. I figured it was the oil from around the threads that had leaked into the cyl.
The smoked cleared after 2 days and ran great for a week. Now its doing the same thing again real rough idle and and its extremely sluggish. I can put the pedal to the floor and she barely wants to move almost like the tranny is going out but the rough idle leads me to believe its and engine problem. I have the check engine light on but can't get any codes. I also tried checking for vacuum leaks by spraying either round the intake and vacuum lines and didn't notice any change in rpms so I'm guess the vacuum is fine.

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?).

Lately I have noticed a lot of blueish smoke coming from my exhaust at idle mostly while warming in the morning though it would do it if the truck idled for a few minutes. I took it to the dealer because I have fords ESP but the tech couldn't get the truck to smoke and wasn't getting any codes so he sent it back with a clean bill of health. After getting it back I noticed it smoking again so I picked up the egr valve kit pulled the valve and cleaned it as best I could and replaced the seals, that was last night. This morning it was blowing more smoke than it has before and has continued all day whether cold or warm. I just changed the oil last week and it's still full so it isn't burning any. Head gaskets were done along with studs last month, egr is obviously intact, cat is gone. I'm really at a loss for this, It's an 07 f350 scsb 6.0...

I have a 2001 F-350 w/7.3. There was excessive smoke coming from the exhaust. So the first thing I did was to pull the glow plugs to see what they looked like. and while having them out I cranked the engine over. Upon doing so I noticed 1 cylinder putting fuel out of the hole. Meaning it was like you could put your hand about 6 inches above the hole and your hand would be wet from fuel. None of the other cylinders was like that. So what I did was pull the injector from the cylinder next to it and put it in to see if it was the injector failing. But it was still doing the same thing. What would cause this??

I noticed a rough idle after driving an hour with a 6000 lb trailer and stopped at an offramp. Had no performance issues to that point in an hour drive. Then I noticed a good amount of white smoke coming out of the exhaust. The idle felt just like when I had a contribution/balance code on #5 a year ago, and a new injector fixed that. Before long (10-20 minutes later) the idle got real loud, like a big knock/loud tick every revolution.
I had a bunch of stored codes, so I reset them and later found a P0281 - Cylinder 7 contribution/Balance and P0404 - EGR control circuit range/performance were the 2 that came back. I drove it 2 more hours to get home. It ran well under load, but coasting or stopped gave the loud knock, and stopped and idling was a rough, inconsistent idle. It even stalled on me 3 times when braking for a red light (auto trans). There was a lot of white smoke all the time, plus a little dark smoke on acceleration.
What would you recommend for troubleshooting steps? I could put a new injector in #7 and clean the EGR valve, but want to have a good idea that will fix it first. Is there a good chance I have a messed up piston in #7 now?
Codes I cleared:
P0148 Fuel delivery error
P0234 turbo overboost (i know i need to pull and clean the turbo anyway, unrelated to today's issue)
P0281 Cylinder 7 contribution/Balance
P0404 EGR control circuit range/performance
P0670 Glow plug (I had the module unplugged a while ago)
P0683 Glow plug (I had the module unplugged a while ago)

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.

2002 F350 7.3PSD, lariat 4x4 dually , 212k miles, automatic, crewcab, bone stock other than k&n filter in factory air box.
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 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.

Early 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

I just looked back and it has been since July 7th that my girl has been sitting in my shop. Well this past weekend I finally got her back together and started. It took a while to build pressure but she finally came to life..
While I am thrilled that she is running again i have low power before the boost kicks in and is idling rough with a blueish- white smoke coming out of the exhaust. Once i kick her a little she will get up and go but I've never had the smoke before.
I'm thinking maybe a bad injector???

I have a 2001 7.3 that almost has everything practically brand new... new hpop, water pump, uvch, gpr, glow plugs, icp sensor, ipr sensor, cps and new turbo pedestal that was leaking oil, well now my truck has a cold start to where it has to be plugged in to start and when it finally does it smokes white pretty bad, misses and sounds like it's jumping around under the hood up until it warms up and revs fine with less white smoke but still a miss!!
Compression on test has been done, and good, fuel pressure is good, but the buzz test when cold shows 123457 muffled and quite and when the truck is warm only 3 and 4 are still muffled and quite? Injectors sticking?? Or just need New injectors!

I've owned this vehicle since new and never overheated or had any major mechanical issues. It just hit 130,000 miles and recently completed a 1500 mile uneventful road trip running great.
The other day I noticed an excessive amount of steam/smoke coming from the exhaust while sitting at a stop light after recently starting the vehicle. Once the van was up to temperature the exhaust steam/smoke cleared up.
I checked the radiator level and found it was about a qt low, and did not seem to have any exhaust bubbling or fumes in the radiator.
Then, I pulled the dipstick and the freshly changed oil looked a bit cloudy (I got really nervous), I really can't say its milky colored because I can still see though the oil and see the cross hatches on the stick. But it doesn't look like new oil.
The engine seems to be running fine, no loss of power or missing. Starts and idles fine.
Talked with a mechanic friend and he immediately said blown head gasket or intake manifold was allowing water from one of the four corners where the gasket seals the water jacket, into a cylinder.
Since that first episode of excessive steam/smoke it hasn't reproduced the problem to that degree. It does start to steam out the exhaust after about 5 minutes of starting cold, but seems to dissipate after the engine warms.
The amount of smoke / steam in that first episode, I couldn't see the car behind me in the mirror ... I looked like a mosquito fogger.

2005 6.0 & noticed on Friday there was white smoke coming from exhaust that started when I'd turn on truck then aster 1st light or stop sign it would be a cloud of white smoke. Once I start to drive it stopped & I didn't see it again that day. I noticed the same thing again on Saturday & Sunday but the smoke was thicker on these days but would stop like the day before.
I had a code come up a month ago which I believe was P404 but read something about EGR valve. So I replaced the EGR valve 3 weeks ago & light never came back.
Today I had a Dr's Appointment and had usual white smoke in morning but once I got to the Dr's appointment the truck sounded like the turbo got louder then usual and started to see cloud of white smoke again. While sitting in parking lot I check to see any codes but nothing came up but the cloud of smoke started.
When I left my appointment, the turbo sounded louder still and noticed white smoke every single time I stopped at a light or stop sign.. Then the coolant level was high with the engine giving me the warning of over heating coolant or something 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.

Having trouble with 6.0 powerstoke white smoke out exhaust. We have installed egr delete and still have white smoke and water coming out of exhaust not as much as before. Took it back apart to see if we did anything wrong everything look ok. We did a compression test on all cylinders they check out ok.

I have a 12 F150 with the 5.0L. it has 27000 miles on the clock. Noticed twice a small puff of white smoke coming out of the exhaust and decided to check the oil level and it was a quart low. The last oil change was done at 23000 miles and used Full Synthetic Pennzoil and a K&N filter. Called the local dealership I purchased at and they told me NOT to use full synthetic and should only be using Motorcraft semi synthetic with a Motorcraft filter. I know the dealerships will only endorse and advice Motorcraft products but what does everyone else use and think. In the meantime I added a quart of oil and all is fine.

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...

I have a 98 with the 4.2.The troubles started with popping a little through the exhaust ,bogging down and bucking,rough idle and had the two codes together that deal with having bad intake gaskets don't remember the codes offhand.
I also noticed every plug in the truck was wet and black however it didn't appear oil wet.I have changed the fuel filter,spark plugs,lower intake gaskets,plenum gasket ,injector o rings,checked injector ohms all were 16.5,new EGR gaskets,all bolts are torqued to specs
Now I have a no run condition, it will crank but not run. I heard a pop in the engine one time. I cranked till the battery went dead.I also noticed as I was calling it a day last night the radiator reservoir was empty. I don't know if somehow I got a hydro lock even though I put new intake gaskets in it or i have some other issue like timing or something. I don't know where to look next....
