Looking good so far! When I did the coolant fill on mine, even though I used a vacuum pump to fill it, I still needed to constantly add more fluid after driving. I think I added 4 litres after it said it was 'full'
The engine looks good in there. I was confused because in your previous post you said '12 cylinder hybrid', I though you were using an Audi V12, but I assume you meant the V8 and the car it was in is a 4 cylinder, hence '12 cylinder hybrid' I thought it was optimistic that a V12 would fit...
