I did open each injector to check, and the sound persisted.

Could this be caused by timing chain stretch throwing of IP timing?



Pressure is at 1.3-1.5 bar @ 90C @ idle ---> 3.0+ bar at 2000rpm with 5w-40 Mobil 1 Turbo Truck Juice.

I understand that poor bearings would cause lower oil pressure than this, is this true?
