White smoke even after warm up
No it's not using any oil and just changed air and fuel filter a few days ago but haven't noticed any difference. Pretty much stock straight pipe exhaust, bm boost fooler and k&n air filter. I use fleetgaurd fuel filter. Smokes heavily at start up even on a warm day. Could it be an injector issue?
Unfortunately the only real fix for a bad injector is to pull it and either have it rebuilt or replace it. If you can figure out which one is bad you could have a local injector shop rebuild it. The best bet is probably to pull all of them and have them tested.
my advise is to pull all 6 and send them to industrial injection for testing and repair. The truck will be down while 1 is out, so pull all 6. That way you don't wind up here again in 3 months.




Have you looked for a cracked fuel line or any kind of leak in the fuel system? It could be sucking air into the fuel.
