oil dilution is a definate possibility for the oil pressure drop. might want to check out the lift pump, a fuel pressure guage would be a major benefit. it is possible you have a couple different problems. i would suggest checking the lift pump first(i worked on an 05 that acted very similar with the white smoke haze and erratic throttle response)...it had low fuel pressure and a lift pump resolved the problem. i would also change the engine oil and filter and monitor how the oil pressure reacts. if its fine for the first couple of days and the more you run it it starts dropping psi more and more, then you may be getting fuel into your oil.

 

Ok I will try that to but my oil pressure stays steady and the truck dont smoke but does have a slight miss untill it warms up for 15 min or summn then it smokes while idleing and has a loss of oil pressure but cant feel the miss nemore. But I think im gonna jst try replaceing all the injectors and see what that does. I also need to kno how to tell the diff in a 2004 and a 2004.5 and if neone has ne injectors for sale I am interested.

 

How wld b the easiest way for me to check my injectors to see which ones is bad im gnna try to replace them myself and jst dont want to haveta pay a arm and a leg to have them checked.

 

My dad has an 05 CDT and he was having similar issues with his. His truck had, at the time, 247K hard miles (tows heavy alot). He replaced all of his injectors, and that cured the problem. That was roughly 6-7k ago. Just preparing you for the inevitable. Sorry.

 

Injectors. Need to stop driving it ASAP!!

 

save the money to have them checked and go ahead and replace them all. they wear pretty evenly and if you replace three now you will have to replace the others very soon. best bet is to go in once and be done with it.

 

Alright thanks guys I will try to go ahead and replace them all and hopefully it will take care of my problem.
