I ran 1 qt Lucas synthetic lube and 5 qt castrol edge 5 30 fully synthetic. Knock still there. Dpfe, egr, all good. Sounds like knock is up top passenger side. Any ideas? Stuck lifter? Cam phaser? Truck starts up on first try. Just cleaned maf sensor and iat sensor. Increased performance. Engine loss power between 20-30 mph and 60 - 70 mph. All is good except knock. HELP! Open to all suggestions. Lastly, no obd 2 codes. Emissions is a green light.
