Front hood making annoying vibrating noise

At warm up engine rpm’s, those rpms cause the area up front to vibrate making a really annoying vibrating noise. The noise settles down after the engines rpm’s get to a certain point. If I pull the hood latch or press down on the front of the hood, the noise goes away. The vibrating noise is right up front under the hood. I’ve checked around that area and can’t see any obvious source of the noise. Any ideas where I should check?

 

Aren't there adjustable hood stops in the leading edge of the hood?

Suspect adjusting those down would help. This thread solved another problem, but it has a pic of what I'm trying to describe.

Making sure the latch is well lubed is a good squeak deterrent too.

 

Try putting, squirting some white lithium on the hood latch hook and pivot point. I had a squeak driving me crazy a while back and that flat stopped it. I also shot some into the hinges too. It fairly certain it was the latch, probably the hook on the loop portion. Good stops were fine also.

 

Look for these. They keep the hood tensioned so it doesn't rattle around on the latch. Your latch could also be worn out.
