I have a ticking noise coming from the engine,

What is your question?

The noise sounds like a lifter or rocker needs adjusting, it is most noticeable when the engine is winding down to idle. I have asked the Toyota dealer to address it, and they tell me I am hearing the fuel injectors. It is the standard SR5 model with 6 cylinder engine app 35,400 miles 2018

What makes this problem better or worse?

Less noticeable after engine warms

How long has your 2018 Toyota 4Runner had this problem?

Since purchased 2 months ago, with 32000 miles
