Is that possible or am I stupid? Its not hard to yank valve covers...

I listened to the vid. I have heard that exact noise come from a broken rocker. sounds like combustion popping back through the intake.
Jake pull valve covers. and if you find broken rocker or pushrod, pull intake too cause I guarrantee the intake port is melted to shiiieet from the combustion coming back through the intake. I know this cuz a scorpion rocker broke on me and did this exact thing!!!
