Here's my scenario.
I bought the car 10 months ago (April). Saw that the previous owner in January had the ticking issue and got the lifters replaced. Since April I have only put about 2,300 miles on my car (about 5,000 miles since the lifters). I heard the tick once a couple months ago and again 2 days in a row this past weekend. I have new car warranty until the 20th and CPO until 2014. I Started my car today (50 degrees) and let it idle for 10 minutes and no tick.
I have a video of the tick over this last weekend, but is it even worth going to dealer for such a rare issue?
