Ford 7.3L Power Stroke (1999-2003) :: White Smoke Blowing / Smells Like Fuel And Loses All Power

I 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?

Ford 7.3L Power Stroke (1999-2003) :: White Smoke Blowing While Driving?

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.

Ford 7.3L Power Stroke (1999-2003) :: Running Rough / Started Blowing White Smoke

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.

Ford 7.3L Power Stroke (1999-2003) :: White Smoke / Clicking Noise And Steadily Losing Power

I have a 7.3 Excursion, 234K Miles, 4R100 Transmission. Today I was in a rush to take one of our dogs to the vet, when I hit overdrive going up a hill, it almost sounded like a clicking noise and I was steadily losing power. I came to a stop sign and put it in park and it started to develop a constant lope that was rough. Whenever I would step on the gas it would put out white smoke which it has never done before. I was able to take it a couple miles before it did the same thing except this time it shut itself off.

Recently I have been having transmission issues as it feels im losing first gear. A while back I noticed it would idle slightly in park every now and then. A couple days before this happened, I came to a stop and my truck started loping slightly and first gear IN DRIVE felt very very weak. I have recently replaced the cam position sensor as well as the ICP sensor. I'm at a loss, I plan to do a ZF6 transmission swap very soon and this is only making me panic even more.

I never dog the truck, take it mudding, etc. Oil is changed every 3-4,000 miles. I did however get it scanned a while back and I believe two codes came up for two pistons, also did an injector buzz test and they all sounded strong.

Ford 6.0L Power Stroke Diesel :: 2003 - Lose Power / Coughing And Blowing Bluish White Smoke Then Shut Off

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?????

Ford 7.3L Power Stroke (1999-2003) :: 2002 - White Smoke On Start Up / Quick Smell Of Oil?

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...

Ford 7.3L Power Stroke (1999-2003) :: 2002 Excursion Puff White Smoke While Trying To Start

My beloved excursion is 300 miles away from me in a no start condition. Vehicle has 270K miles. Very well cared for. No issues to date since purchase 5 years ago. Went to back up and the vehicle starting Caming like it had a big cam in it. went from reverse to drive and problem went away. Drove vehicle for 2 more weeks without issue. Then all of a sudden it dies. Restart driver on down the road 1/4 mile, dies again. Restart, make 45 mile drive home vehicle is low on power will hardly pull a grade but I got to my friends house. Went to start vehicle next day and no start. Puff white smoke while trying to start. It hits every once in awhile but wont run.

The vehicle is throwing NO CODES other than an open glow plug on 1&8 which it has for sometime now. I have changed, fuel filter, fuel pump, CPS(genuine ford), IPR and IPS. No real changes still wont start. I disconnected the IPS and it started but it sounded like it was only running on a couple of cylinders. It would not accept throttle. The local Forddealer does not have a Ford diesel tech. Ive called a couple of diesel shops and I hear could be a bad HPOP, or bad ECM or a bad IDM but without seeing it. I am at my wits end with this thing. I am an electronic engineer by background. So I have a good sense of the process. I have checked all fuses, relays, etc. I will say I did have one issue with it a year ago where the UVC problem popped up but the dealer fixed it and it has been fine ever since.

Ford 6.0L Power Stroke Diesel :: 2007 - Power Loss When Driving - White Smoke Blowing

I have an 07 6.0 with 400,000 miles. Has been a great truck with no major problems. Before I started the work I had 3 bad injectors, running rough and the oil/ coolant temp just outside of 15 degrees. So I tour her down and replaced head gaskets, installed arp studs,all new injectors,all new glow plugs and new oil cooler. Ran great for a couple days. Then when driving to work lost power on and off for a few miles then completely gone could only go 10 miles an hour. I checked codes and there was the under boost code witch has been on there for a while and I forget the other code but it was for the ipr valve so I replaced the valve and right after still the same but that code went away and the p0470 popped up. So I cleaned out the ep sensor tube and replaced the valve. After several miles she now runs great but now I'm getting a little puff of white smoke when I take off and not every time and mainly when I take off some what quick. All codes are gone expect the under boost. I have an egr delete already.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F450 - SES Light Came On Followed By Loss Of Power Under Load And White Smoke From Exhaust

I have a 2001 F450 7.3 chassis cab with just over 100k. I have a new problem... So far on two different occasions the service engine came on followed by a loss of power under a load and white smoke from the exhaust. Took it to the shop the first time, they determined it to be a dirty air filter, which seemed odd since it just happened all of a sudden. They changed air & fuel filter, problem gone- for two weeks..

Ford 7.3L Power Stroke (1999-2003) :: White Smoke At Idle When Warm

I 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?

Ford 7.3L Power Stroke (1999-2003) :: White Smoke At Startup Even When Its 90 Degrees Out

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.

[URL].....

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?

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Smoke White Randomly?

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.

Ford 7.3L Power Stroke (1999-2003) :: White Smoke / SES Light Comes On When Accelerate

When 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.

Ford 7.3L Power Stroke (1999-2003) :: Tough To Start And A Lot Of White Smoke

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.

Ford 7.3L Power Stroke (1999-2003) :: White Smoke At Startup And Knock When It Warms Up

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.
