This year of truck had a problem with the cam phasers and oil pressure, there is a new cam phaser solenoid that works under lower pressure, but you should aslo check the camshaft bearing surfaces for wear and also do a oil pressure test on the engine with a mechanical gauge, the oil pressure needs to be 25 psi or more at idle with a hot engine.
