Noisey Fuel injectors

[mbalbritton]

I know fuel injectors can have a noisey tick to them, but how loud is normal? It's really kind of annoying. sounds like the engine has an issue, but it runs like a champ ('08 Honda V6).

I thought I needed a valve adjustment, but they checked out within spec.

Audible with hood up, inaudible in cabin. Cost enough?
