I just bought a 97 f150 4x4 4.6L v-8 and keep having problems. The check engine light came on saying that it is running too lean. The truck had been sitting for a while so I changed the air filter, maf, and pcv valve. After changing the pcv valve it is now blowing white smoke. What can be causing this to happen?
View 1 RepliesI have an 01 f-150 4.6 triton and it now blows a sometimes pretty big ploom of white smoke at start up. Sometimes it smokes for a while after that and sometimes not. It runs smooth and strong but I have no clue what to do...

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!
As the title says, leaking/blowing gas from exhaust. Here's what i have done so far...
Compression check: 145 to 150 across all 6 cyl
Fuel Psi check: 65psi
New plugs, wires and injectors along with new intake gasket
Checked for vacuum leaks and found none
Starting to think headgasket but coolant levels were normal, but not driven for a couple miles after the misfire/smoking gas smell started.
I have fire, compression and to much gas, the spark plug on #1 looks clean, #2 show more black and 3 thru 6 look blackish/normal. I am at my wits end on this.
SO, I've owned a 92 f250 7.3 for 10 years and it's got over 340k miles on it. Well, she is getting tired so I'm debating replacing the truck with a SLIGHTLY newer model.
I've found a truck that is a 99 7.3 powerstroke with a 6 speed manual and 260k miles. Knowing these engines I feel this truck has at least another 100k in it if the thing was somewhat taken care of. The issue is that the fella that has it for sale says it ran great for years and one day started blowing white smoke while driving. Other than this new issue it runs fine.
So my question is, what could be the issues causing the white smoke? I always thought white meant unburned diesel or maybe antifreeze. Head gasket comes to mind but it's not something I've ever dealt with.
I like that he parked it when it started having issues. Sounds like someone who doesn't completely trash their vehicles. Too high given the condition? Truck looks and sounds pretty good aside from the smoke, pretty reasonable condition.
I have a 7.3 that's running rough. Started it the other day it ran alright but started blowing white smoke. Bought a oil and fuel additive i was going to run through it. Came a few days later, it stated up and was real loud and sounding like it was loping. It blew a good amount of white smoke, but it just smelt like real heavy diesel. Now i can only turn it over and it won't start.

View 3 RepliesI have a '98 Expedition with 170k, 4WD, 5.4 and auto trans.
I drove me truck home about 15 miles and sat idled for 15 minutes while on the phone. The truck started running rough all of a sudden and then died. I tried to restart it and would crank over, but not ignite. I thought fuel pump, grabbed a can of starting fluid and eventually fired up, but was huffing white smoke. After about 3 minutes, it sat there and purred. No problem, right?....
I dropped it in reverse to back into the driveway, when I put it in drive.....nothing, no forward gears now..? It will start up and run now, but still no forward gears. I have a leaky heater core, but rarely have to add water......and no milkshake in the oil.
The truck is a 98 4.6l with 188,000 miles on it and yesterday i was driving up over a pretty steep grade hill, i was going about 55 and turning maybe 2800 rpms at the top a big cloud of white smoke came out (either tailpipe or just out of motor on hot pipes)and also some in the cab. It didn't run any different though so I kept driving about 3 mile and stopped where i could take a look and and saw fresh oil around the starter area running down where the motor meets the tranny. I checked the oil and it was at a good level and also not milky. I checked level again today and it seems well and there is no drops of oil on the ground i ran it home about ten mi and it runs good. What could have happened?
View 2 RepliesFor over a year, the truck took 5-6 seconds of cranking to start, but always started. This morning it started, but shakes, coughs, and vibrates like hell. It revs up but still sounds like its hitting only on a few. replaced ciols many times over the years, but this sounds different.
View 6 RepliesI 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 RepliesI am a mechanic and tow operator running a late 99 f350 7.3 6 speed cab and chassis wrecker. This truck has had a hard life and has been neglected for quite some time, and now has become my baby/headache. Truck starts great, idles nice, and will run great for about 5 minutes until it starts billowing white smoke that smells like fuel and loses all power. If you continue to drive it it will die. Sounds like it's dropping cylinders and will barely idle. If you stop for 5 minutes or so and let it idle it will smooth back out and will run great again for another minute or two, then right back to stumbling.
Using torque app, hpop pressure looks good when it's running well. Peaks at 3k, IPR maintaining 30-40% max. As soon as it stumbles you can see the hpop drop to 5-600 and the IPR will climb to 65%. Let it idea bit and they go back to normal, and stay good until it stumbles again.
Ive changed the fuel pump, ICP,rebuilt FPR, change fuel filter, pulled and cleaned the fuel tank (metal tank, no delamination, looks perfect inside). Pickup screen looked good. Cleaned the IPR, cleaned the hpop reservoir, there was no screen inside. Checked voltage at fuel pump, 11.78 across the pump with it running. Pulled valve covers, no noticeable leaks around injectors. Injectors have less than 5k miles. Remans with 100% larger tips.
To me it seems like the lpop is not keeping up with the hpop under load, starving it until you idle and let it catch up. Could it still be bad injector orings? Bad lpop? Something I'm not thinking of?
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 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 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.
I picked up a 2003 6.0 awhile back went ahead and did studs,gaskets, delete. Was driving it and seemed to lose power, started coughing and carrying on blowing bluish white smoke then shut off. Ended up hydrlocking #5, Oring on injector was tore when took out. Put all back together, ran horrible, did a balance test with AE, showed #3 injector, replaced, ran horrible, did AE dropped #1 injector. So in process of replacing the rest of the injectors. Just wondering why it is or was dropping them 1 at a time. Ficm was showing 47.6 to 48.6 volts, could that be it?????
View 14 RepliesMoving my worldly goods from California to Oklahoma in a rented 26' box truck with my wife following in our '02 F350 loaded to the gills with my lathe, mill, air compressor, weld and assorted machinery. Just west of Deming NM it started to blow lots of white smoke and down on power. Some rattling noises from the engine when throttled up & won't reach 3000RPM.
Had it towed to an impound yard for storage. Plan on sending a flat bed to pick it up when we get to Tulsa.
Any experience with a tilt back trailer capable of loading & transporting this truck that weighs around 17,000 pounds? My plan is to continue on to Tulsa & make arrangements from there.
I have a 2006 F350 6.0 litre diesel. The other day I started it up drove away and it was blowing huge plumes of white smoke out of the exhaust. Shut it off.....started it up again after a while then went on a long drive and it went away. What that was?
View 6 Replies2006 blowing white smoke and sluggish until its driven for a few miles ..smells like fuel .. New head gaskets and the works started after 20 days over below freezing temps nights at 5 to -5 ....
View 14 RepliesMy 2006 6.0 is blowing white smoke/steam and Im losing coolant (not out the top). Pulled the EGR valve and its wet down there. All signs lead to EGR cooler? I've been reading a lot on this forum and Ill do the oil cooler at the same time. I seems VERY important to flush the coolant system before I tear into this. I am afraid of hydro locking the motor or ruining the head gasket or stretching the head studs if I run the truck. How can I do this without further damaging the engine? I am doing this myself. I'll have 3 solid days to finish this job because I have to tow my trailer in 5 days.
