So I have committed a terrible sin.....I bought a 05 CRD almost a year ago and read the newb section then changed the oil and the fuel filter and didn't do anything else.
The Jeep and I had a rough start to days after I got it the transmission blew up!! It only had 85,000 miles on it and it was toast after fighting with the dealer for a week they paid to put a new AC condenser, all new lines and a new factory Dodge Trans in it with a 100k mi warranty. I had been in a small front end collision and pinched the line from the AC to the transmission and it overheated the trans and smoked it. So 3 weeks later I got it back and it has run great until about 2 weeks ago.
Oh the dealer had to have the entire EGR assembly and turbo replaced right before I bought it, I saw the work order and everything was all nice and shiny.

So it had plenty of power and I love the thing it had big shoes to fill as well since I sold my 99 7.3 Powerstroke and got this.

Anyway about 2 weeks ago I was driving and it started losing power every now and then. Now it is really sluggish off the line and if I punch it it blows a ton of black smoke and has a huge turbo lag before the power kicks in. When driving in a normal fashion it is just lacking power and if you need to accelerate quickly it doesn't want to do it and it takes forever for the turbo to kick in, and then again a bunch of black smoke and it has never smoked before.

I searched the forum and have done the following:
1--I did the EH Mod and ran it to the front. (I am going to make a DIY provent because it is dropping a ton of oil) It seems to be dropping more than people on here say they get out of it.

2--I ordered SAMCO hoses from boostcontroller and they came in today. (Looks like the turbo side one was original and really soft. the other side was the newer mopar one.I will replace them both with bright orange SAMCOS dunno if my color choice was the best lol

3--I got a GDT Eco tune last week and loaded it. It does idle different and feels a bit better but still not its old self.

4--Tonight I took all CAC hoses off and the hose that goes from the airbox to the turbo had a big crack in it (maybe that is the issue not sure) I am ordering it tomorrow from the local dealer and I will replace it when I do the SAMCOS

5--I cleaned the MAP and MAF sensor again the MAP was gunky but not as bad as when I got it and cleaning it didnt fix the smoke and underpower issue.

6--I felt inside to the valve that the driver side CAC hose hooks to and it moves easily but is pretty gunky I may need to take it out and clean it.

So I now have the turbo hoses off and the coolant overflow off of the Jeep. I am wondering if I should just get the airbox hose and put it all back together, or take off the turbo and clean it and the EGR assembly off the other side and clean it out before I put it all back together. I hope something here fixes it. I miss my old power, and I know there is something going on with it.

The only code it has thrown was a P0299 turbo low boost.

Any ideas would be greatly appreciated. Sorry the post is so long

The hose going from the air filter to the turbo is a known problem.

Fit all your new hoses and take the Jeep for a long hard drive (Italian Tune-up) to clean the turbo out and maybe your problems are resolved.

First off, welcome to the forum!

Secondly, x2 on the put it back together and drive it idea.

You really want to work on one area at a time in order to isolate the problem(s). The air hoses, i.e. fresh and CAC, are known areas for failure. With all hoses installed and tight, especially the CAC clamps (did you get the up-graded t-bolt band clamps?) take that mongrel out and and do your level best to dent the floorboard with your right foot!

WAIT!!

Make sure that the oil is up to snuff. Are you using good oil and filter? Is it fairly fresh? Taxing the mongrel without good lubricant will make for an expensive run.

Hope this helps.

"Why guess when you can know?"- Carroll Smith

CRITICAL - as I understand it you purchased this vehicle 1 year ago with 85,000 miles on it so I would guess you are close to 100,000 miles in which case you absolutely must do a timing belt replacement at that 100,000 mile interval or things can go south quickly and get expensive. With care and proper tools or proper substitutes can be a weekend DIY project especially if whereever you are there is an experienced member nearby.

As to your current issue I beg to differ a bit on the suggestions. Yes the airbox to turbo hose tear is a known problem and needs to be fixed ASAP as the turbo should not be ingesting unfiltered air but that tear has nothing to do with P0299 or low boost. Low boost comes from:
1. bad turbo - doesn't sound likely in your case
2. bad CAC hoses - as one of yours was real soft that could be the problem
3. intercooler leak - possible but not highly likely; if other things don't fix your problem it wouldn't be that hard to lightly pressurize the intercooler to check for leaks (see Sir Sam's NOOB guide timing belt change writeup for a possible leak spot)
4. leaks in the FCV/EGR area - also possible but tend to be visible due to leaking oil mist in the boost air
5. bad boost pressure solenoid or collapsed/melted vacuum lines - fairly likely, see what I just posted at viewtopic.php?f=5&t=70602&start=80
6. sticky turbo variable vanes - per GDE "You can check the vane functionality at idle in park. Underneath the vacuum actuator on the turbo is rod extending downward connected to the vane mechanism. If you pull off the vacuum line at the turbo, the arm should drop about 1/2 inch and then raise back up after reconnecting the vacuum line. It is a bit difficult to see the rod, but this is the easiest method to check for proper VGT vane moevment." and the fix is usually the Italian tuneup.

Ok sorry for the delay
I put new SAMCOS on it (pics soon they are orange)
I put a new air intake hose on it
made a homemade provent to keep oil off the ground
Installed eco tune
Changed the oil and put Amsoil 5 40 in it and new Amsoil filter

Went out and drove a bunch say 200 miles and it got better but not back to normal. It was much better and never threw the 0299 code. So last Thursday I had to drive to Vegas (about 500 miles 1 way) went down with no issues and got 25 mpg so not to bad. I have been back for a few days and still no issues until this morning.

Headed to work and got maybe 2 miles away and CEL came on I am used to this by now(checked it when i got home only the 0299 again). I went to pass someone and noticed a ton of smoke behind me and then lost power like it was doing before, but it never gained the power back I couldn't go over about 40mph I pulled over and noticed that there is a yon of oil pouring off the bottom of the turbo. I turned it around and limped it home. I have been looking at a few posts on here about similar issues and I am thinking it may be the lines under the turbo.

I think I am gonna pull it in the garage and strip the turbo system off it and see what is going on, since I am tearing into it that deep I guess i will order the timing belt kit and do all that at the same time, and take off the EGR side as well and check all that out. If I am lucky my new job will start by late next week and I will have a company car so I can have time and not have to rush on it.
I will get some pics up soon let me know if you guys have any ideas or have had a similar issue.

It frankly sounds very much likethe case I had.
The origin was the vacuum line that got closer to the engine.(by offroading or my mechanic moved the line).
Here is a thread on it.
Look close at the line all its way. Specially under the protections.
