Engine Help!! Cracking Noise

[WheelManATX]

(help) Help! I have a Crackling noise coming from my engine during rev or acceleration...

Does it mean I'm running to lean? or what???????(help)

crackling like water dripping onto hot valve cover or crackling like there's stress fracture somewhere

When I'm idle i don't here it

Sounds like a exhaust leak.
