Hey guys this could just be the cold weather and me being ridiculous but I thought I'd ask anyway. When i started the car yesterday in the cold weather and heard a new noise. It's very consistent but goes away once the car warms up. It almost sounds like a rattling/scratching right around the timing cover on the passenger side. Could it be the cold weather causing it? Or is one of the pulleys possibly about to go out? Like I said just curious for insight cause I know if it's one of the tensioners I need to get it taken care of. Thanks
