odd noise @ 4000rpm's

[scandmx5]

This is annoying the piss out of me. Whenever my needle hits 4000rpms, Im getting this odd "sshhhhh" noise. The only way to describe it is like a sizzle/ putting water on a hot skillet or stove. It doesn't matter if Im accelerating,decelerating, shifting, it always does this.

Exhaust leak? (manifold?)
Vacuum leak?

[scandmx5]

OMG simon with a non humorous answer
im honored
yeh, my 1st guess was exhaust leak- but not only @ 4000rpms, it would be across the board.
vacuum leak would surely produce a CEL, im assuming?
it did in the swedish stallion

wrong about the exhaust leak happening across the board. my car has an exhaust leak, and it literally sounds like a turbo spool. http://www.youtube.com/watch?v=sjWwz_Ivneg

High pitched rattling / buzzing? Pilot bearing. Mine does it too.

[scandmx5]

thats it
i could only describe it as sizzle lol
**does it cause any major damage or affect clutch/rest of tranny, or do i have some time?

[miataspeed69]

you have time. I did my clutch and didnt do the pilot so i had to do it again but my pilot was bad and i rode on it for 6 months or so, but it was alot worse than that.
