Hi guys!
I have a 2005 3500 RV conversion with the OM647 engine and about two weeks ago I started to notice a few things with my van that weren’t there before. Van has 191k miles.
Another thing to note is that I am not getting any codes and all of my fluids and filters were changed before starting the trip out west.

- From a stop it is pretty slow to rev up until turbo pressure builds up and then it takes off. This is especially true when the engine is cold.
- Idle seems to have gotten a little rougher and increased a bit. I can feel a slight pulse in the steering wheel that wasn’t there before and I can potentially hear a faint noise through the dash from the injector area that is in sync with the rough idle. This isn’t noticeable on the tachometer and seems to smooth out when driving.
- At highway speeds it seems to downshift more when going up inclines than it use to. Previously, when going up an incline it would stay in 5th gear and build up boost. Now, it will shift down to 4th to maintain speed and on some of the steeper 6% and 7% grades in Colorado it will even downshift to 3rd trying to maintain speeds.
- Occasionally during a cold start there is a brief smell and some exhaust smoke. Both go away after a minute or so and aren’t noticeable when the engine is warm. I haven’t noticed any leaks under the injector cover.
- Over the past two weeks the engine has developed a pretty noticeable clacking sound. It doesn’t sound like rod knock or a spun bearing, but it is a very distinct noise that wasn’t there before. This seems to go away mostly once the engine is warm too.
Another thing to note is that I am not getting any codes and all of my fluids and filters were changed before starting the trip out west.
