I have a 2004 Dodge 2500 5.9 cummins with 250000 miles. I jst bought the truck and it starts a little rough not bad though, and it holds a good oil pressure with no white smoke untill it warms up. Then it starts to blow white smoke while idleing or at low rpm with a loss of oil pressure not bottoming all the way out though. If you idle the motor up or while at or over 1200rpm it quits white smokeing and I gain my oil pressure back. Also if you rev up to say 3000 rpm it will stay there for a cpl seconds after you let off the paddle then it will idle down some and stay for a sec then idle on down. But truck seems to have plenty of power and runs out pretty smooth for the most part.

 

id say injectors are bad. but im prolly wrong

 

I sure appericate your opion. If neone else has a opion on it I wld sure like to hear it I need all the help I can get because I am new to all of this and I jst dont have the money to take it to the dealership and let them guess at it untill they get it fixed. Everone who takes time to look at this and leaves me a opion it is much appericated.

 

does the truck throw any codes? use the key trick and see what ya get.

 

No it doesnt show necodes the check engine light isnt on, and what do you mean by the key trick im new to diesel trucks.

 

Sounds like injectors to me, is your oil over full?

 

the *key trick* is with the key. turn it. "on" "off" ''on'' ''off'' ''on''
and in your mileage center it will show you codes. like for show. p0963 and then write down the codes and post em in here. sometimes your truck will throw codes and not turn the light on.

 

No my oil is not over full im sure of that, and thanks I didnt kno nething about the key trick, I have one of those code scanners and it didnt sho nething and I also checkd it on a bully dog system and nothing but I will check it that way to.

 

sounds like injectors to me.

 

Yep! Sounds like bad/ worn injectors and possible oil dilution.
