I was tracking down some issues in my engine and discovered that 7 of my Scorpion 1.6 billet roller rockers had cracks at the roller pin. Scorpion rockers are generally regarded as top of the line and included in many crate motors; Roush, Smeding, CHP, Keith Craft,etc. A couple of my buddies checked their Roush engines and each found one or two with the same cracks.
Without hesitation Scorpion agreed to replace my entire set and the individual rockers for my buddies. The replacement rockers are beefier around the pin where the cracks surfaced.
