... Where the noise is coming from, as if something was stuck inside a valve spring (Around cylinder 4)... I wish I had a better look when I had the lifters out. Or poked around with a magnet. Ahh regrets!
Seems like the best guess at this point. Ill try and figure this out further. Or just have at the Drivers side head and check the valve assy
