First, welcome to F150 Forum!
How many miles do you have on it? The oil pressure should be the highest when cold, so I would expect a worn timing chain/tensioner to make noise
when hot. This would be the same with the cam phasers. First thing I would
do is use a "real" oil pressure gauge, and see what the oil pressure is doing cold & hot.
You're not running a Fram oil filter are you?
