What's your oil pressure reading? The only moving parts under the intake manifold are
1. The cams, which would be about where you are describing
2. Lifters, which normally start to "tick" as opposed to squeaking
3. Pistons, which wouldn't squeak
4. Rods/bearings, which would be more of a "bottom end" sound
5. Crank. Same as above.
Take a video, post it up, and we'll try to narrow it down. You're sure it's not coming from the front of the engine?
