My car has a (relatively) loud ticking noise that occurs most often when the engine is cold (after sitting overnight or all during the day) and the outside temperature is cold, usually less than about 45°F. On an unusually warm day, over 65°F, the noise was barely audible. This morning it was 19°F when I left and was between high 20's to low 30's when I returned home and the noise accompanied me the whole trip. If the temperature is in the 40's and I let the car warm up for an extended period of time, it is somewhat quieter. Is this just "normal" valve train or timing chain tensioner noise? To me, it seems excessively loud even for an inexpensive car. Except for the first two oil changes (and the most recent) where I used non-synthetic 5W30 oil, I have been using Amsoil 5W30 with Wix oil filters. I've also been filling up at the local gas station most of the time, a Shell station, with 87 AKI fuel. Lastly, the car is equipped with a CVT and has just over 19,000 miles on it.
Does anyone else have this loud lifter like sound, or any suggestions as to what it might be, and if anything can be done about it? Otherwise I am fairly happy with the car.
