The engine is fully ready for rebuild, I'll not bother with removing the crankshaft or the piston, I'll leave this to the experts.
From my point of view, even if the lower part of the piston is broken, the cylinder wall seems ok. I don't think I'll need to get it machined, but once again, I'll leave this to the pro.
Now seing this really make me question if a want everything forged.. Maybe just the pistons, just because I don't want to redo this engine ever again 😅
Here is where the problem was all along, I have no idea how this happened..
For ref, here is how it should look like
Can't wait to start the mini again, it's like an itch in the back of my neck that I need to scratch for 3 years now !
