2013 C63 Little End Failure
A video of the noise would help on here too, I see quite a few used engines going for around the £7000 mark on ebay so that is always an option but tbh if two different dealerships gave that opinion I would be going to an Indy shop such as MSL to see what they think as that have torn down many a M156 to fix and tune. The last time I was there Acid had at least 8 C63 amgs getting work done just to show you most the guys go there and travel from all over (I go from West Yorkshire to Birmingham)

I came from the S65/S85 (M3/M5) world and when the rod bearings gave out on those you would have metal shavings sent everywhere via oil passages. This required replacement of the entire oiling system (hoses, cooler, VANOS solonoids, etc) along with full engine replacement.
Did they put a 30WT in for a few changes by accident?
I'd just crack the fuel line and go for a rip. Let er burn...
If you try to rebuild, you will have an early recurring bearings problem. Because shavings will come out of some passage.
But it's not only the engine that has to be replaced. Any external oil cooling items like pipes and radiator have to go as well.
That's also why, as a buyer you have to be careful with buying used engine blocks and internals, oil radiators and turbos (for turbo cars).
