Ford 7.3L Power Stroke (1999-2003) :: Still White Grey Smoke After Replacement Of Rings On Injector?
Jan 28, 2016
I replaced the rings on all 8 injectors put in 8 new glow plugs and a relay. My truck is still putting out grey/ white smoke at start up. It goes away after about a minutes. Truck runs a little rough a first then smooths out. I know some smoke after doing a job like this is to be expected but I was thinking I t would go away by now. I've been running through my head what I might of done wrong but I can't think of anything.
Does it just need all new injectors and not just rings ?

I have a 2002 F350 7.3L w/superchips programmer, k+n cold air intake. Does NOT smoke a lot from tailpipe
Not running rough since I changed my oil to rotella 5w-40w synthetic.
Appears to have good amount of blow by coming from the oil fill when engine is warm.
Can Bad Injector O Ring(s) cause blow by and oil consumption?

Truck is a completely stock 2002. New injector o-rings, glow plugs, valve cover harness, and injector cups a year ago... all motorcraft parts. New batteries and starter in the last 6 months.
I've checked the GPR both at the relay and harness got power all the way to the valve cover harness on all 8. Injector buzz test sounds okay as well.
Had a stuck IPR issue a few moths ago that caused a CEL and died while running. Took apart and cleaned the IPR and CEL is gone truck runs great once started and has correct IPR pressures in all RPM ranges.
Truck runs great once it is started and is not sluggish until warm like when it was hard to start when cold with leaking injector o-rings.

Just picked my 2005 excursion from being bulletproofed. Arp studs, oem head gaskets, turbo cleaned rebuilt, blue spring mod, 8 new Motorcraft injectors, rebuilt heads surfaced, new Ford oil cooler, egr plugged delete, sct x4 on 2nd tow tune, new radiator, new fan clutch, new water pump, and sinister delete kit. I got almost home to last stop sign and took off and noticed grey/white smoke.
Then drove so more for 20 minutes. Everything you come to complete stop and take off it does this. On start up it will puff a little puff then go away. Is this normal after a rebuild and go away after some miles have been put on engine. Or should I be worried. It runs awesome now and idles so smooth with tons of power on tow tune.

ok so about a year ago and 7 thousand miles ago (abouts) I did a engine build and rebuild I had brand new injector cups, injectors (180/100's) and new o-rings......now I've got fuel in my coolant and smokes like a freight train in the mornings white/grey I believe (its dark) but never black smoke but not the smell of coolant like unburnt fuel truck starts up amazing at 10 degrees' when I had the machine shop building my heads for my stg 1 cam I had told them not to install my cups well they did anyways and used red locktite when I keep hearing and seeing recommended to use green and have used green in the past
I know most situations are cracked cup, cracked heads, my biggest question is ya think the red locktite will hold? And since the cups are new could it be a injector o-ring? dosent the fluids on the injector go botton to top (coolant-fuel-oil) and a bad oring mixing the two I did notice my fuel psi was sittin higher liker 75 psi iv lowerd it since then

I didn't notice anything until I was towing yesterday and tried to pass a car to get onto the offramp.
Anyway, I went to floor it so I could get around and, in my mirror, I could see a decent bit of grey smoke coming out. What could it be?
It doesn't smoke at all on startup and runs smooth right away.

Rebuilding my 7.3 and I'm in need of the removal and install tool for the injector sleeves/cups for the 7.3 Powerstroke Diesel.
I'll pay all shipping charges and a small fee if required. I hate purchasing a tool I'll never need again, rather better not need.

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.

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?

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.

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.

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.

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?

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.

My 02 excursion is missing at idle and jars the whole truck around going approx 50mph feels like good amount of power loss but still pushing 30psi boost, just got autoenginuity all injectors buzz fine on the test, contribution test show balance fault in cylinders 1&8, should I look for o-rings to be bad, uvch, cups cracked or what ----- turbo fine, hpop great condition, new IPR, new fuel pump and hutch mod, about. 250k miles on truck nothing else major showed up on ae.

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!

I just replaced my up pipes, turbo pedestal O-ring, ICP, IPR, New O-rings in all my injectors and torqued to spec, new glow plugs, glow plug relay, oil loom wiring harness, new O-rings on oil cooler, oil filter, oil, and antifreeze. I have tried and tried on upwards of 75 or so time to get it to turn over. A little white smoke came out and it sounded like it wanted to fire up, but only a few times.
I have good batteries and a charger on it, 3-4 tries in 5-10 second bursts or longer if it doesn't lose power every 30 -hr. oil is in HPOP too. just found out my block heater is dead, but I shouldn't need it now. Tach moves a little when I crank it but only when my oil pressure gauge hits half way and that about the time it wants to start and starts white smoking.
