2000 7.3 white smoke

I know you have had endless questions about white smoke and I have read many of the posts. looking for advise on diagnosing possible causes. truck has 186k on it and has smoked white with raw diesel smell on cold start since I bought it last summer. I recently replaced all injectors with full force "stage 1" and replaced both valve cover gaskets, wiring harnesses, glow plugs, and pig tails. added a hydra chip for single shot tuning. truck starts WAY better in the cold now and seems to run very well warm but still smokes quite a bit on the first start of the day until you drive it about half a mile. should I pull valve covers again and make sure they are all shooting equal oil? do you think this may be a compression issue? any help is appreciated.

Maybe the glow plug relay? Or some have the module. Might not be getting enough juice to the plugs. Or working at all. My fullforce injectors took a while to break in so to speak. Mine smoked a bit at start up, but blue fuel not white. Whats your tune, maybe its a bit rich? Normally if you contact the company they can email changes that may help, once they know what its doing. Jody adjusted my tunes no less than 6 times before I was happy. White is usually air in fuel, but you'd have a leak if that were the case. And you said fuel smell , so im guess its rich until a certain temp then the tune leans it out. Probably to make it idle smoother with the single shots. Jody dropped my idle pressure to 487psi , and it smoothed it right out, almost stock sounding. But that made it smoke when cold a bit, so I keep all the tunes so I can have a variety. Good choice on injectors.

I forgot to mention I put in a new stancor gpr a couple weeks prior to the rest of the parts. it seems to be getting full voltage across both large posts. I just have their standard tunes on it right now but it seems to run great after it warms up. a little black smoke if you get on it quick but no other issues when warm. this white smoke on cold start was a large part of the reason I decided to replace all those parts. it seems like it might be only 1 cylinder causing the smoke. looks like it could almost blow smoke rings for the first few minutes it runs.

Watch all your fluid levels close. Installation of injectors is easy, but a slight mistake can be real bad. Your going to have to get a scanner to do some testing. But if its smoking so much it blows rings, that's a lot. Could you have cut or rolled an O ring during installation? Did you do the cups too? how did they look if you didn't? Cracked cups? Most important is to watch the oil level, and smell for diesel. Sure sign of a broken or leaking injector. So many things can cause this. A scan tool for ford would eliminate a lot of them. Could be as little as a bad sensor.

Well I got my ae with the ford bundle now. Ran a buzz test and they all sounded good. I did not replace the cups they looked fine to me. I only have about 500 miles on it since the injectors and an oil change but I'm not seeing any changes in oil or coolant levels. What should I start looking at with the ae?

Unless its a valve issue, you would know if you have blow by simply by opening the oil fill at idle. Put the cap on top upside down. If it sits still other than engine vibration, no blow by. If it dances around but stays on, alittle blow by. If it pops right off, you have blow by pretty bad. Passing that, compression test would still be good to eliminated valve issue. KLhansen is better with the sensor data, but he usually wants live data of ICP, Duty cycle, Pulse width, oil pressure, rpm, temp. Start the data cold, and record until operating temp. Helpful to monitor were on the data the smoke begins and ends. Contribution test should tell you which cylinder is not performing. Klhansen should chime in soon, or pm with the issue and data. You can monitor each sensor live while its running, it may be obvious if theres an issue. Did you ever ask if your tunes could be adjusted. Still sounds like the cold tuning is off, if its fine else where. Klhansen will probably mention it if he sees it in the data. If he doesn't chime in , PM him.

okay. thanks a lot for the help. I'm still trying to figure out how to use and save all the ae data. I have looked at the blow by and it's just like a very gentle mist out of the oil fill tube. not enough pressure to do anything to the oil cap. I pulled the valve covers off today and all of the injectors are spitting out at least some oil at idle. only ran it for maybe 5 minutes. even with both bay doors and the man door open my eyes were burning and nose running. I'm very happy to hear it would most likely be a valve issue if it is a compression issue. doesn't look too terrible to get the heads off. do you think I should order a compression tester or wait to see what the ae data says?

I did not ask about other tunes yet. it had this white smoke before the injectors but maybe not quite as bad. I was hoping the injectors would solve it but now I'm thinking it's a separate issue.

well I tried starting it up with 1 injector at a time unplugged today and let it run for 10-20 seconds for each cylinder. I didn't notice much of a difference in the smoke with any of the cylinders unplugged so now I'm even more lost.

Did you get data , Pm Klhansen? Since your in there, did you pull injectors to see if you have a cracked tip, or burnt tip? Seem to be asking a lot of questions, but not taking any advice. You have the tool, send the data. Did you call full force and ask them about it. I did. Had Jody change my tunes. All said before, nothing done. I'm out.

no. I don't have any data to send yet. still have to figure out how to do that with the ae. haven't figured out how to find/pm people on this either. I have never really been any type of forum member before. I called full force and they didn't think it was anything to worry about and said if it idles well and doesn't smoke after it warms up its pretty normal to have white raw fuel smoke on the first start of the day. said I could check the compression and that he wouldn't be concerned with anything above low 300s on a cold block. compression tester was delivered today but I'm working out of town. thanks for the suggestions.
