Mines noisy in cold weather too. It seems to have a faint whine noise going thru the RPMs, but once it warms its fine. Its my 2nd winter with it, and its the same as last yr, so I call it normal.
decent quality parts and oil right there so probably not the issue. It's almost impossible to diagnose this over the internet. It could be anything from busted timing chain tensioner, to loose heat shield, to perfectly normal. Goodluck.mobil 1 5w-30 sythetic and pureolator filter.
Well, it's not loud. I didn't have this car last winter so I didn't know what the vehicle sounded like when it was actually cold outside.
it's not loud mechanically, just more noise until it gets up to temp
