Strange noise from motor
 

Long story short this noise came about roughly a month ago. I thought maybe plugs were failed so I replaced valve cover gasket, spark plugs, spark plug tubes, crankcase vent hose because I broke it remove the vc, valtetronic shaft sensor gasket, eccentric shaft actuator seal and the noise is still there. It sounds like a dirt bike and the noise increases as the rpm’s increase. It’s noticeably louder on cold starts, any guesses?

Post a link to a video or post a video.

While doing that, also pop the hood and try to locate the approximate area its coming from.
