Same here. Doesn't rattling when engine is cold. Only when hot. From reading different forums they suggest it is a vacuum pump.not sure. Can you post video?

Good news! By camshaft pulleys you mean camshaft gears at the right side of the camshafts under the valve cover? Were they much worn out or there was gap between them two? How much for a new parts? Where did you ordered them? Was it a big job to change them over? Do you have to remove a timing belt? Thanks
