For 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 03 250 5.4 with 160k. I just recently replaced #4&3 coil packs. Truck was running great again. Then a few days later the truck was running extremely rough and white smoke from the exhaust. I noticed the pcv valve was not all the way in(pretty much out) put it back in and ran fine for two days now running rough every now and then and the pcv valve is making a vibrating noise but stops if I pinch it slightly. I did replace the plugs a year ago.
View 14 RepliesI 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...

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?

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.
View 1 RepliesI'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.
My 2001 7.3 is smoking only when barely on the gas. New fuel filter. Don't know if its possible injector going bad or what? Smoke is white not black.
View 1 RepliesI have a Tymar intake, magnaflow exhaust, a DP Tuner and I have Rosewood Diesel injectors.
I had a bad oil leak recently and it seemed to be coming from the turbo area so I changed all the o rings back there and deleted the EBPV system (I cut out the butterfly and welded the holes shut, cut the part of the pedestal that held the actuator because it looked like it was leaking and welded the oil holes in the pedestal that fed it. I left the actual EBPV sender in the pedestal and kept it connected to the harness)
After all that was done I checked the oil and it was low but still on the dipstick so I drove it to the local parts place to get some more oil, about 2 miles, because I wanted to check for leaks. It was not happy, ICP low code came up it was sputtering and jerking when stopped at a light. I got to the store and parked it, it took about 3 litres of oil and seemed to run pretty good after that.
But on the way home I noticed a bunch of white smoke, I figured maybe an injector was stuck. I started it a little later and no white smoke in the driveway so I thought maybe it had gotten lubed enough and had sorted itself out. That was a few days ago.
Today I started it and let it idle in the driveway for about 15 mins and no white smoke, I wanted to get it up to speed a little so I took it to do an errand that was about 10 miles away, lots of lights and a bit of highway. It would run fine while going at speed but as I would slow down for a light the ICP would go down to around 600psi and the white smoke would start, as sitting idling a huge cloud of white smoke would form (yes, I was that guy), once I could take off and get it running a bit harder it would go away again.
I am assuming that I have a stuck injector (or cracked), I have no oil in my degas bottle and it doesn't look like it is fuller than before. Seems like I may have used more fuel than I should have, but pretty hard to tell just from the fuel gauge.
I have tried a buzz test and they all sound the same, tried a Compression Contribution test, no codes from that.
How can I locate a stuck injector? If that's what it is?
I have long been having troubles with white smoke at startup, even when its 90 degrees out. Long story short I've got new glowplugs, GPR, UVCHs, valve cover gaskets, injectors, turbo, valve seals, valve springs, and HPOP all within the last year. Most of those parts were needed, some maybe not so much. After installing injectors things started getting worse, whether they're related or not I'm not sure yet. I pulled passenger side valve cover off again in an attempt to figure something out and heard this coming out of the intake spider.

The strange thing is it goes away when it warms up. I should also note the reason I started with the passenger side is because I did a compression test and this side had the lowest readings, with #5 being 270 psi. I disconnected each injector one at a time on the passenger side to see if it made a difference while running but didn't really notice a difference. Am I looking at a motor rebuild, or at the very least a head removal?
my 2000 f350 7.3 is acting strange lately. Its got 252k and is all stock other than exhaust,intake,ww2. It smokes white every random once in a while for some reason. At start up it wont though. If i get on it every once in a while it will smoke white then go to back to black. Im not consuming coolant, and the oil looks fine, no residue on the oil cap and its not puffing out the oil cap either. Other than that its running great just dont know why it goes white every so often.
View 14 RepliesWhen my 99.5 SD is cold ( 50-60 f) it smokes a lot of white horrible smelling smoke for the first 2-4 minutes. If plugged in the block heater it doesn't do it. Also when cold, when you accelerate the SES light comes on until you let off on the throttle then it goes off. Even going 10mph in low rpm? Once engine is up to temp it doesn't do it anymore. It seems to run fine otherwise. I do have 2, 700 CCA Napa batteries that are from 2011 which I plan on replacing next month with Motorcraft Maxx 850 CCA.
I have replaced the UVCH, CPS, Fresh Oil and put additives in my fuel. I have even disconnected my DP Tuner F5 and it still does it. I have AE with ford bundle and it seems like my HPOP seems to be working fine as well as buzz test and glow plug. Could it be an injector ( I have stage1 casserly from full force)? What about a sensor not working? It has always smoked since I have had it ( about 3 years) but the SES light issue has only been happening since my IDM was replaced and I had a mechanic work on it.
For the past few days I noticed my truck would be really rough to start and a lot of white smoke. but once it ran for a minute or less it would be fine. Today when I got home I popped the hood and was looking for anything and noticed my degas bottle had this weird fluid inside on top of the coolant? So I popped the cap off and smelt it and its fuel. Of course this would happen to me. Now I'm not going to lie I have beat on it a few times this week but nothing so so serious.
Could this be contributing to it? Could it be a head gasket? now being a diesel mechanic I doubt its a head gasket simply because there is no oil mixing. I am praying its nothing too major. Once I have the narrowed down to what it could be ill see if its something I could tackle or if the stealership has to do it, which I am not looking forward to. I'd rather be down a truck for a little bit and save a boat load of cash.
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.
So my truck a stock 2000 7.3 started smoking when I would start it up in the morning... figured it was a glow plug issue. Checked the relay it was good, checked the glow plugs found 2 were bad replaced them.
Thought I was done, well I started it up and took it for a drive. still smoked... thought no big deal I know some oil leaked into the cylinders doing the glow plugs.
Then it started rattling like a lift went out, no more smoke though because the truck was warm... shut it off at my buddies. Limped it "it actually still drives ok" 5 miles home.
From my research it sounds like an injector. I have tried a buzz test and they all sound the same.
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!
