I also have this issue but the rough idling was rare and intermittent so I didn't worry too much about it.
Now I'm getting CEL and Check VSC lights. Took it into Autozone to get the codes pulled and I got a P0101 (throttle body??), P0171 and P0175 (02 sensor??). Disconnected the battery, reconnected and the lights went away for a couple days and came back today. Car is a 06 250 AWD with 110k miles.
Is this carbon build up related?

I am going to wait til 69000 miles before going for this piston/ring/block replacement route. Although I have the occasional stumble @ read lights, My engine revvs so smooth that I fear that once they open it up and do all the messy things, it will never be the well oiled smooth revving precision machine again.

I have had an 08 250 with 54,500 miles for 8 months. I had the break down done in April for the carbon build up. After they had it for three weeks, I finally got it back. My alignment was messed up and my car was smoking out of the tailpipe. I called my service adviser immediately and he said to bring it in and they'd fix the alignment but the smoking was normal as it was simply the chemicals from the break down burning off. I went on a test drive with my mechanic who did the break down and he WREAKED of weed- I had to roll my window down because it was so bad. My car continued smoking for two and a half weeks and oil started coming out of the tailpipe. In addition to that, the oil smells like gas really bad. Now I'm really freaked out so I bring my car in despite what my service adviser was saying. They take the engine out and start the second break down in a month- really great. I met with the service manager and told him about my mechanic smelling like weed and my car is now smoking and has been for nearly 3 weeks. They drug tested the mechanic and he's no longer working there... thank goodness. Got the call yesterday that pistons 1 and 3 were filled with oil because piston 1's rings were lined up when they need to be staggered by 120 degrees and piston 3's rings were in upside down. The dealership has fully admitted fault and is trying to simply do the tsib again but that's not good enough now. The short block needs to be replaced as does the entire exhaust system since it's got oil jammed all throughout it. I want a buy-back by the dealership because this car has been messed with too much and I have zero faith in them because of everything. When I came into the service dept for my first oil change, they lost my car for 4 hours and it ended up at an upholstery shop 10 miles away. Another time I went in to pick my car up, there was a dollar-bill length black scuff on my front bumper. What the hell are they doing to my car??!
TL;DR- Dealership royally messed up my engine on the car I've had for 8 months and I now want a buy-back. Justified? If so, how much is reasonable to ask for?

You want a buyback on a car that's 4-5 years old and you've only owned 8 months... because you got an incompetent mechanic at the dealership?
That's probably not gonna happen.
I'd certainly raise hell about getting everything relevant fixed/replaced and maybe a free extended warranty for your trouble though.

Hi there, just wondering if anyone has ever attached an aftermarket PCV oil separator and remove the condensation on a regular basis? If anything this should reduce the amount of water going back on the valve, but requires a lot of dumping on a regular basis.

Forgot to mention- there was a significant amount of gas in my oil and I drove it like this for almost three weeks. Met with the service director and service manager yesterday. They're trying to put me into a 350 because of the issues caused by their mechanic. We will see if that actually happens. The district sales manager is supposed to call me today or tomorrow to get the ball rolling.

Nice! Im not a mechanic but is it possible to check if you have any carbon buildup without taking the whole engine apart? or how can we check it?
