Okey soo today after an awesome day out at Marwell zoo on my way home my car all of a sudden started making quite a loud blowing noise but at the same time a rattling/ grinding noise coming from the engine the rattling/grinding noise is louder when I release the accelerator. I've got a sound clip of the noise I hope that helps if anyone can help and tell me what they think the problem is that would be great.
