So I finally completed my project E93. Sorry the sound isnt amazing and the shots might be a bit close up as I did this on the floor but I'm hoping it'll help someone still.
The issue with it was my oil pump on the gearbox had broken up inside and this led to the flywheel (aka flexplate) to bend and rub against the engine block, or timing chain cover making a horrible squeeking sound. Well it's all been covered in this video which I hope can help others with similar or related jobs. Feel free to ask any questions.
