blowing white smoke

the truck has been blowing a steady stream of white smoke, i thought it must be oil but a diesel mechanic said it smelt like unburnt fuel and he thought fuel must be getting past the injectors and into the cylinders. Does that sound right? if so should i replace the injectors?
also theres oil in the turbo the mechanic i talked to said he had heard theres a seal on the hpop that goes bad that will cause that but he wasn't sure does anyone know for certain?

had a friend come out and one of us hit the throttle while the other one watched the exhaust, when you lay on the throttle it blows out clear so its when its idling that its blowing smoke, he says he thinks the smoke looks blue but i dont know to me it seems white

im having a similar problem with my truck and was told it was most likley my injector o-rings. i bought a kit to replace all the o-rings on all 8 injectors for 57 bucks on ebay they are alliant brand. ill be doing mine this weekend ill let you know if it helps me out.

also if you have a scan tool like snapon or a few other expensive brands you can do a contribution and buzz test. it sounds to me like you just need o-rings from what i have been told / read about online.

looking at fuel injectors and where can if find the date on the truck to see if its 99 or 99.5? I know theres a sticker on the door but the doors are off a different truck so where else can i find it? And after what date is it considered a 99.5?
not going to buy injectors till i'm sure it needs it, just want to make sure i buy the right ones the first time if i have to

youll have oil visible in your turbo unless you do a ccv mod to keep the oil mist being vented from going through your turbo and intercooler. i would start with orings on the injectors and keep your truck as far away from the mentioned mechanic as possible. the HPOP doesnt come anywhere close to pumpin oil into your turbo. How many miles are on your truck? original injectors?

In sure guys have gotten more miles outta injectors but i only got 115k from my first set. I would say if you have time to do it twice try o rings first and then Plan on settin money aside for injectors if that doesn't fix your problems. Does the truck run smooth and start fine still? If it sits overnight is there a large plume of smoke when it first fires?
