I can only describe it as a constant chirping noise (subtle) that appears >2000 rpm. It comes from behind the valve cover near the injector rail(not injector chatter). It sounds like a vaccum leak...but I cannot find one.
any advice appreciated thanks in advance

strange wistling noise
Re: strange wistling noise
Grasping at straws here....do you have a Comptech Foam Filter? If so, that may be the source. I have a turbo like whistle from my car at certain throttle positions because of the comptech filter.

whistling noise
No, bone stock..but thats a good way to describe it...its like a turbo whistle,,only subtle.
whistle
Im going to go out on a limb here and assume the worst.
I know we have loads and loads of intellegence on this board..Ive seen the pics from the Expo
So the whistle has a Hz property, It tends to run in cycles. It starts quiet, quiet >= to 1700 rpm and begins to cycle at about 2000 on (a bit louder) My concern is that there could be a bearing that is about to peace-out on me. Has anybody had a bearing commit suicide..maybe you can describe the sounds you heard prior.
One last question, I know honda (type-r in particular) is known for tappy valves, but could the whistling be due to high cycle pinging (made up that term)
Thanks

whistle
sounds like it's possibly coming from the pcv valve.
