      When was the timing belt tensioner changed?

      also check and see if your cam is being lubricated

      now that i listened to it with my home audio. im gonna go with bearings. best of luck

          Check your valve adjustment. Maybe you'll get lucky and one just came loose. You need to pull the valve cover and look at the very least before driving it again, IMO.

                Yeah I check under my valve cover with my brother and we looked and everything seems to be fine. But that noise sounds horrible

                      Take a stick (broom handle) Place it up against the block and to your ear. You can determine which piston is slapping. Up and down the valve cover and you can determine when there is a bad valve, broken rocker, etc..
