My 2008 Ford F150 4,6l 2 valve (205,463 miles) was having timing chain rattle on start up. We replaced, timing chains, tensioners, guides, and oil pump. It's running great now.
C,mon. You can't publish pictures of a spotless high mileage valve train without giving due credit to the oil and the OCI choices of the astute owner. This is Bitog!

OCI has been 4500-5000 miles. Originally ran PYB for first 50,000 miles, changed to Valvoline Synthetic Maxlife, and then to Liqui Moly Special Tec AA.
