Broken rocker arms two weekends in a row

Sure, I always take broken stuff apart to see what/where it failed.
I found it curious that it blasted apart as opposed to just hinging open as other I've seen ,
Good luck .

I'm with you, I've never seen a rocker arm break like these have. I wish I still had the Norris stainless steel roller rockers that were on my old W2 Dart. But I didn't have a spare set of rockers to swap them out with when I sold that car so the new owner is all set in that regard!
