Hey guys, after running the supercharged g37 for the first time today and I went for a drive, there is this weird bubbling/gurgling sound after a drive, it sounds like its coming from on top of the engine. It goes away after shutting the car off for a few minutes and starting it again, its gone but once I drive for a few minutes it comes back again. Please take a look at the video to listen to the sound, I'm clueless on what this could be. It's a Z1 supercharger kit. Please help, thank you guys for your time!
