Not that familiar with this sound. But when you rev the engine, or you are taking off fast. The engine makes like a high pitch compression noise. Ive heard them in other vehicles but mine is louder. What do you think it is, or what to do about it?

2000 5.3L....its coming from somewhere close to the top of the engine near the firewall....the noise kinda sounds like a faster higher pressured version...of when you check your tire pressure and some leaks out

so you don't know what the exhaust manifold is ?
this is where the exhaust exits the engine,,it should look rusty,,with bolts that are rusted mounted on each side of the engine...get's hot quickly...

What about the PCV valve, back of engine, near the firewall, on top of the drivers side valve cover. Is it in the hole correctly? Just a thought.
