Omega General Help / Re: 2.5 DTI running rough
« on: 12 January 2024, 22:22:49 »If injectors are bad you would experience black smoke while accelerating ( M57 runs fine even with 2 or 3 bad injectors)No diesel in oil pan, already checked, no rough idle. When heats up runs very well, critical point is until temp gauge reaches first quarter
There is tutorial on YT how to check them, if you don't want to take it to the specialist.
If your Omega has rough idle, you could start buy disconnecting one by one, and see if there is any difference.
My money would be on a Turbo, or something around it (check for oil in intercooler, hoses, clamps,)... White/grey smoke usually mean oil in compression chamber.
Another possibility is that high pressure fuel pump on it's way out, which I doubt. Check for diesel in oil pan.
