Very true, but also the injectors used on our trucks are loud too! An
injector tap is higher pitched than a valve tap. I didn't know our valves
were adjustable, thought they were hydraulic and didn't need adjustment.. On
my truck I thought too I had either run low on oil(hence tapping lifters) or
worse. Started poking around with a stethoscope and found that:
1. Timing chain was going south(repaired)
2. The injectors are noisy li'l buggers.
Just my 2 cents....
