Volvo D6 310 Low Rev vibration

[volvopaul]

True. I did hire a volvo engineer with the diagnostics but as I said at the beginning he didn't even mention or notice it...
We should be in discussions about it but he's not bothering to answer my emails...however there are no fault codes so maybe its just a "feature"

You don’t need a vodia to see or hear a misfire .
Did he carry out a cylinder balance test on the inspection that would tell you if there’s a cylinder down on compression or faulty injectors.

I don't notice anything like that on my 310, on an outdrive, maybe sounds a little harsh on load starting to come on the plane. Is there anything loose anywhere that might be resonating at that particular frequency? Not necessarily on the engine.

Worn or loose engine or gearbox mounts?
