I have a 2007 Tundra 5.7 with 45,000 miles on it. I hardly drive it, because I have a commuter car. I drive it about twice a month putting only 100 a month. I do not tow or haul, maybe once a year. I have new oil in it (Mobil 1 5w20). During start ups when I have not driven it for a week or two, there a a noise like something is not getting lubricated. Once the engine is going everything is good. After it starts up and I do some driving its like normal and the start ups are Ok, for instance if I go to the store, when I start up, its Ok no noise. I only here it when the truck has been sitting for a few days or weeks. I also tried some experiments....I would drive it all day and the next morning start it up and its fine no noise. Then I drive all day and start it up a week later I hear the noise. I know this sounds weird, but I want to see if anyone is having similar problem. I still have a warranty but the dealership I go to is dumb as rocks.
