My new 2015 f150 with 5.0 less than 3000 miles has a itermittent. Lifter noise. I was towing my camper last weekend and when I came to an intersection. It did its hill decent thing and downshifted. When I started to accelerate it made a loud ticking sound. It lasted a couple of seconds. My wife said what was that! I told her it sounded like a lifter. What a bummer new truck and sounds like and old truck. Then yesterday I was towing again and sure enough. At around 3000 rpm it started ticking but more steady i could hear it more as I stepped. On the gas and when I let up just a little i could hear sound less. Both times it happened after I had towed around 60 miles. Has anyone else experienced this issue. Will it possibly go away with time. I changed oil between these two instances hoping it would help. I am using motorcraft 5-20 synthetic blend and ford filter. I'm worried that dealer will say no code so we can't fix it! I hate to have a brand new engine ripped apart. Has anyone else experienced. This problem? Any info would be appreciated. Thx

 

Most likely considered "normal" by dealer. Welcome to 2015.
