Hey guys, I bought a 2012 f150 in December of last year. Picked it up with 70,000 miles it currently has 83k on it, completely stock. Last weekend it started ticking and it's definitely wasn't something that was there before. It's not a terrible loud ticking but enough that I'm concerned that it wasn't doing it before. I travel for work so I put on around 800-900 miles since the problem started. No change in noise and runs great. It only does it at idle and seems like more noticeable when warmed up. Any advice would be appreciated! Thanks!
