Hi all so i wasn't sure if this was the right place to post this....mods fix it if need be... but anyways. SO i recently bought a complete y7 block. Knowing very little about a motors condition based on appearance and not knowing the guy i figured i would just trust him and buy this motor which he claimed he pulled from an old ladys car and only had 108000 km's on it. It was also out of an automatic so i figured i would be safe. So upon further inspection the harmonic balancer was missing there was just a cirle of rubber there? the turque mount was ripped. And upon removal of the head instead of finding a paper head gasket there was a metal one there. Once the head was completely off i looked down in the cylinders and there was a lot of a black wet flaky materiel i could literally scoop up with my hand. Also down in the water jacket there is a blue/green coating in certain spots on the walls. I turned the motor over and the bottom end seems tight. SO afterwards i cleaned out the cylinders as best i could and it seems that there might be some scarring at the very top....just wondering if this motor should even be considered for a rebuild....?
