Does anyone know what this could be? Made a short video to show what is going on at https://youtu.be/-PwmKCfjOH4 . I bought a wrx engine suppose to only have 45k to 65k for an 02-05 on it and internals are warrantied for 30 days. Was thinking avcs but from what i checked it doesn't have that. Sounds like spring but as you can see in the video it only makes that sound when the top cam is in proper spot. Which doesn't make sense because there not anyway connected??? Im lost?
