Wh en I started it on a sub-zero morning recently, it made a loud ticking noise which went away after about a minute or two. There is plenty of oil in it and on previous starts, it did tick a little bit, but on the very cold day, it was loud enough to make me think what the heck was going on. The light goes out right away after I start it, and a Caddy service manager said that it's normal for a Northstar engine to do this. I just think that Cadillac should get these engines dialed in so they don't sound like some clunker when theyr'e left out overnite in cold weather. This morning I started it in the garage and it made a light ticking noise which went to a quiet idle after a very short time. Thanks, Frank
