OM606.961 - Missing at idle whem warm
OM606.961 - Missing at idle whem warm
I have a recently developed problem with my OM606.961.
Starting cold everything is fine and the car idles well.
When warm, and specially with air conditioning on, the car has a lumpy idle. The engine even shakes the car with a rocking motion. If I open one door I can even see the door going up and down due to this.
Another symptom is a great difficulty in starting the engine whem warm. It sound like it starts firing in 2. then 3, then 4 and finally 6 cylinders.
And another one: In 500 km's the oil level dropped from full to half. After this the oild level doens't drop so much, but If i get the level to the max, it digests the oild really fast.
Engine mounts are new. 4 or 5 months ago I took the intercooler out to clean it and a significant amount of oil was inside it and inside the entire intake system.
If I unplug the oil vent tube that connects right before the turbo, I can see a significant amount of oil vapour jetting out.
The car has 485.000 Km's. Is it time for a rebuild or a new (used) engine?

no damaged/worn engine will play as u did reported, when hot. and it is oil related, no engine will stop burning oil once it starts.
but there are mysteries,
u can start watch the idle hunting when hot? if so is diesel missing. air bubles in the system. O ring failure.

Now you got me mind blown...
Never heard of that one...
sometimes the EDC pump , the back where the electroactuator is, gets worn of and u have unsteady idle, but that can only be corrected by changing the electroactuator, or pump or overhaul the thing.
that is something u dont want to do. u should make sure the problem is there and not in a faulty O ring.

couldn´t see or hear nothing wrong with that engine , except the fact that it is smoking a bit, wich is kind of normal for that mileage.
