Default Need help White smoke at idle Loss of oil pressure

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.

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.

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