I've had this really annoying and loud noise under my hood for a while and from the researches i've done on this board i'm assuming it's the crankcase ventilation valve, or the PVC valve, and its hoses and pipes.
I really need help right now to make sure that this is it before i order the parts , anyone with experience would be a great help.

Here's the video clip with the noise, i tried to aim at the place where the noise is loudest. Any thoughts + verifications would be helpful.

the noise is the loudest when it's in drive or reverse, in neutral or park it's not as bad. also when i give it a little gas the noise disappears.

that's a ton of noise. the first thing to buy is a mechanics stethiscope to isolate the exact location of the noise. then replace that part.

i asked another member on the forums he said the noise just gets louder and louder until it throws a check engine soon light.. but shouldnt necessarily damage anything else.. just low MPG and bad performance.
