Some 2011-2019 Mustang and F-150 vehicles equipped with a 5.0L engine may exhibit a ticking noise at idle after an engine oil change. It is often referred to as typewriter noise because of its similarity to the sound of a mechanical typewriter. The noise in question may be heard on some engines when engine temperatures reach 150°F (65°C) or higher and engine speed is at idle up to approximately 1700 RPM's. It can typically be heard at the front wheel well, and is often isolated to the transmission bell housing or oil pan area. typewriter noise is not detrimental to engine function or durability and has no short or long term effectson the engine. This an operating characteristic of the 5.0L engine and no repairs should be attempted.

Wow, this is the single biggest complaint I hear whenever I take the Mustang to the dealer for service. An "operating characteristic of the 5.0L engine and no repairs should be attempted"?! Touch wood, I haven't had this issue yet.
I have a feeling I know what you aren't having that issue.
