Heads up guys
So I had a Scorpion rocker arm break on me. It didn't break at WOT, racing or anything like that - It broke under the lightest drving conditions possible. I was cruisin down the freeway with the cruise control set. The check engine light started to flash, I turned the radio down and heard a loud ticking noise then I was stranded at a gas station for 8 hours. Here's what I found when I pulled the valve covers. Thought you all might be interested in this......

That sucks man. Glad it didnt take anything else with it
Slowest in Oklahoma...
Well ive never like the idea of aluminum rockers for a DD.
That's a common failure point on the Scorpions. Why 1.8:1 rockers? The added load from increasing the ratio from 1.7 to 1.8 put a lot more stress on the rockers. If you want more lift you should get a bigger cam.
Bummer deal on the busted rocker, I have the 1.7s on my 408.

DANG! Good thing it was only that and it didn't cause anything else... What happened to the piece that broke off? Chewed up by a valve spring or other rocker? Mess up any valves? If not, you are one lucky SOB.
