Just noticed today that my engine was making a strange sorta high pitched whistle/whine sorta sound near the air intake manifold. the last thing I did with the engine was to install an oil catch can, and I know everything there is sealed right. I'm not really sure what it is. best guess is a hose going bad somewhere. anyways, made a shitty cell phone vid of it where you can hear the sound. lemme know if ya have any ideas.
