Agree.
I don’t really know enough about the differences between valve noise, injector noise, nailing, and vacuum pump noise. And, I suspect that a belt could do it too… if there was a spot on a pulley.
Broomstick is better than a stethoscope?
Where on the VP is the best spot to listen, if it is coming from there, it means what, that a bearing is loose in the race?
