Does anyone else get this engine tick? It only happens after the car is warmed up. It is noticeable when you are slowly cruising at low rpms like your driving through a parking lot. It sounds like someone typing on an old school typewriter (for the young folks

). I have 0 engine mods to the car, just suspension, and axlebacks.
Park Cities ford said it was normal and not a big deal. It makes my car sound like a hooptie when I'm driving through parking lots.
Here is a video of it (hopefully). You can hear it at about 13 seconds
