The injectors on mine are quite noisy, as long as they all make the same noise at the same frequency I'd say they should be OK, it's just the noise they make opening and closing. If they were gummed up they'd be quieter if anything, as they wouldn't be opening / closing properly.

The black plastic shroud that covers the injectors is there to drown out the noise. They are low impedence injectors and always sound loud to the point where they can sound like a rattley set of tappets, especially on idle.

its defiantly injector noise. but is also due a rebuild as getting smoke at high revs, just wanted to sort the injectors before i look at the rebuild.
