I just bought the truck in November, it now has 99,100 miles on it. I've tried different oil, Valvoline Syntech, Royal Purple with a Wix filter. It dry starts every time if its sat longer than 20-30 minutes if that and then the constant tick and on really cold nights it will have loud lower engine knocking also that will only go away once you start driving it. I let it idle for ~5 minutes and it was still doing it but about 15-30 seconds after taking off with it she will stop knocking. Its driving me insane because I just bought the thing and had no issues or noises when I purchased it.
