GB's question may be a bit of the cart-before-the horse, since you haven't had an A10 engine apart before. First, we might establish if you know what's meant by "crank endfloat". If not, it's the amount of side-to-side play of the craankshaft within the crankcase as controlled by shims located between the main bearing and the crankshaft body (or, "web"). Knowing this value can go a ways to deciding if the engine must come apart, but it's not the only factor.
Before steering you to a link about how to check endfloat, I am curious if there is not a larger bit submerged in the pool of oil you're showing in the sump. It looks as if there is. Then, could you post a picture of all the bits dried out and shown on a clean surface? This might just be delaying the inevitable, but if your intested in more opinions before undertaking disassembly, this would help.
I have to locate the endfloat link after posting this, so, back in a few.
