FYI the "cylinder wall damage " some Toyotas have experienced is from extended oil changes with low tension oil rings.
Stick to 5000-mile oil changes or risk the low tension ring cylinder wall damage as vanishing causing sticking
My 2015 4.0l Nissan engine makes horrible noise when cold started. It has 230000 miles on it and UOA are perfect. I would investigate farther. Started making noise around 80000 miles
