Over the last week or so im trying to track down the causes of my white smoke upon start up, and when you back out of the throttle after flogging on it. The smoke when idling at start up burns your eyes but i cannot make out if its oil or fuel. I have smelled and my sniffer has no answers. It idled the other day for 10 minutes or so after being warmed up and i ran it up to 1500-2000 in neutral and boom white smoke. Dont know it its oil or fuel. I have had injector problems with this truck but would it act like this if i have another going down hill? My intake and everything is clean no oil entering that way. Im lost i had this brain fart and thought maybe my afc diaphram was torn and it was getting back into the motor that way (out there idea i know). I tore it apart and found this... It appears to be oil and why is it in my afc? Im desperate at this point. I have racked my brain and have no clues. I dont really have the place to tear the down pipe off and check if the turbo is slobbering oil or not. Any ideas guys?

 

However with more thinking im really leaning towards valve seals or injectors. My thinking behind this is it smokes on start up. I wouldnt think that there is enough heat to burn the oil on start up if its the turbo. This truck for 15.5* of timing has always had one H*** of a timing rattle. Would injectors with poor pop off pressure setting cause this? I also dont think the egts get as warm as they should with no plate. On a fifth gear pull it takes awhile for it to even hit 1000*

 

i remember that coolant will cause white smoke

 

Its not coolant.. I have been keeping a close eye on everything and no water missing at all.

Here is a video of it hazing. Has been started once and warmed up and then set for about 3 hours and this is what it produces after being started. Do you guys thing this is out of line? The exhaust burns your eyes pretty bad. Im really starting to lean towards injector issues.

if it was oil your smoke shouldnt be white, it would be blue, im curious if it is bad fuel, maybe you got fuel at a different place than usual.

 

Na i get it at the same place everytime. Its been doing it for more than one tank. I run powerservice pretty heavy in all my tanks as well. I think its fuel but the way its acting its hard to say.

 

ok in your video was the truck cold?and is there water in your oil cus that can cause white smoke.it looked like blue smoke in the video.my truck has a haze like that till its fully warmed up

 

Well i have been keeping an eye on the coolant. As of the other day there was not a drop of water missing from the resevoir or radiator. I am starting to say the smoke is a mixture but mostly white. I really think it may be injectors. Im gonna try my best this weekend to get the injectors out and pop tested along with running the valves and other things and try to narrow some of this down. The truck has always hazed when its cold but i feel like its getting worse.
