Smokey start
Hey guys. I own a 2003 5.9 Cummins with 377000kms. I just replaced my injectors and now when it starts a good size of black smoke comes out my exhaust and continues with a hazy smoke while idling. Seems to start, run and idle fine. The only aftermarket part is a 4" mbrp exhaust, no catalytic converter which I got installed only a couple months ago. I've only owned the truck for 6 months. It's my first diesel. Not too sure where to start.
Thanks for reading!

You are good- my truck starts with a puff with 100hp injectors and has a haze if your looking for it at idle. I wouldn't worry about it- seems normal for larger injectors. If you had excessive smoke driving or motor was running poorly it'd be a different story!

Even large performance nozzle injector should not haze or smoke at an idle, that is an indication of poor assembly or poor orifice formation.
