how the hell

do you blow up a /6 six?
I don't know how you can do it, but I managed to!
I was driving along, I heard what sounded like the rockers tapping, just as I'm thinking to myself, wow, that's starting to get nasty sounding. POP!
The damn thing locked up tighter than Dick's hat band!
The thing has plenty of oil, It wasn't overheating, it just started rattling and bam!
I'm hoping that the rocker arm came apart and has the timing chain messed up, I'm not to optimistic.
My mom is in the hospital, so finding time to get the valve cover off is at a premium right now.
Boy, if there is a way to muck something up, I'll find it!
