Hi, does anyone know what this engine noise could be? Im trying to sell the car and i recently lost a sale because the guy thought it sounded like an expensive fix? The noise stays the same regardless if you accelerate and it stay constant while the engine is running, I’ve taken it to take to two garages and both struggled to find the source. Many thanks Chris

Sorry Chris, I will not download anything from untrusted sources. If you would care to put it on Youtube or the like I will be happy to listen to it.
