Hello. If the noise occurs when you accelerate then it sounds like it may be a timing chain problem. Being that this engine does not have a fan the noise typically comes from the timing chain. It may be from low oil or from a chain failure. I typically start by removing the engine drive belt and starting the engine to see if the noise is gone. If it is then it may be one of the accessory pulleys. If the noise remains then it is the timing chain. If you are going to have this checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the noise and recommend an appropriate repair.
