Get the chirping sound going at idle.
Use a section of hose like garden hose or the like.
Use it like a stethoscope.
Locate what side or end of the engine it is coming from.
Work from there.
You should be able to locate the sound with a little effort.
Sometimes a loose spark plug can cause what your describing.

A loose spark plug will cause that.
