On a recent trip I noticed white smoke coming from my exhaust, it is most noticeable when idling and a warm engine. It doesn't smoke on start up and I really can't see smoke coming from it while I'm driving. I replace the injectors about 3000 miles ago, The lift pump about 10,000 miles ago and the injector pump approximately 30,000 miles ago. The engine runs smooth and I haven't noticed any performance issues. It is not giving me any codes at all. Any help would be greatly appreciated.

 

White smoke is unburned fuel. I would have your injectors pop tested. Its possible its got a cracked tip or dumping to much fuel at idle.

 

Thanks, I'll start there. Do you have a recommendation on where to send them? I found a place in Canada but I would like to keep it a little more local if possible and the local shops that I contacted here only do gasoline injectors

 

Any local diesel shop should be able to check them out.
