id be looking at injectors and piston rings.
Sounds like you have blow by, but that's a ton of miles on stock injectors

It could be injectors. Find a local diesel injection shop, take them out and have them tested. Check your oil level to see if it's rising or dropping. How good is that used turbo really?

it is driven every single day like your typical vehicle you drive to work.
How many miles is your commute?

Turbo was an $1800 new Chrysler unit. Was a bummer as I could have bought a hi output one for that money but broke down at the car show and needed it fixed the same day. Well, that's a revealing statement. What happened to the turbo?

How many miles is your commute? A lot! I am self employed and on road all week maybe 40,000 a year. Of course not all in this truck.

[quote=jerseybud]might want to see these guys in bangor http://dieselfuelsystems.com/productcart/pc/dfs-services.aspCorey is a great guy and I have been quite a few times. They are 15 mins from my house. He gets $125 an hour to diagnose so I am just looking for another opinion as Corey simply stated start saving up your money to the tune of about $8000. They have not diagnosed anything yet but I hate to spend $500 to find out I need to spend $8k but that might be my only option. Just tough as I keep getting deeper and deeper in this truck that does not owe anything at this point but I cringe to think how much more I need to put in it...

If it's got a strong pulse of blow by with the oil cap off at idle coming out of the oil fill hole, the engine is hurt. It's more than likely got some broken piston rings. I have had many of these engines apart and it is common with them. Everyone is quick to blame it on a bad injector but that is usually not the case. Especially if they have a POS aftermarket air filter setup on them. They let too much trash in and wear the rings. Once the rings wear they will begin to flutter in the ring land and eventually break. These engines use a keystone tapered style piston ring which when it wears it will no longer fit tightly in the ring land and break. The broken rings will trash the cylinder wall so it will need to bored or better yet sleeved. Most of the time it is just one cylinder and the others can be salvaged with a fresh hone and fresh rings. It is definitely NEW injector time also.

I have also seen inoperative injectors cause a lean condition in a cylinder which scuffs and scores the cylinder wall and piston.

How many miles is your commute? A lot! I am self employed and on road all week maybe 40,000 a year. Of course not all in this truck. Okay, my first thought was short trips when you posted, which will ruin a diesel. I run my '02 Cummins a bit like yourself putting 100 to 300 miles a day on it (empty). In colder weather sometimes the idle would slobber/stumble and the cure is to find good long steep hill, keep it in top gear, and pour the coal to it and make it work. Do it a few times. Mine would smooth out and clean up every time. Easy thing to try before digging into your wallet. It's possible too that you may be on the tail-end of winter fuel in your area, so you can try giving it another month or so just to be sure that's not causing issues. Warm weather and winter blend will affect a Cummins. Otherwise, wow, some excellent diagnosis posted. Sure hope you get lucky and don't have to go that far though. $

A compression test requires pulling the injectors and special tools most shops aren't going to have unless it's a diesel specialty shop. I would do as the previous poster said and pull the oil filler cap, look for a strong pulse of smoke, if not pull the injectors and have them tested.
I guess you could always pull the intake hose off the turbo with engine NOT running and see if the turbo still spins.

Well then you definitely have excessive combustion going past the rings for some reason.

I love those transmissions! Killed two 5.9 Cummins over injector issues, an 04 and an 05. The 04 had an injector go wide open and hydraulic the engine throwing a rod, the 05 had an injector go dead and burn a hole through the piston. They were both due to maintenance issues, the 04 my fault and the 05 the previous owners fault. The fuel filter was plugged up and starved the engine. May be time for a rebuild though as throwing new injectors in it will be a waste of money now.
The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
