Same problem, both motors, broke the roller off the lifter and several other lifters had the needle bearings gone. Second motor broke two lifters, both motors had a little over 1000 miles on them. When I contacted CC they said with the spring pressures I was running, the life of the lifter was 800 miles and 1000 miles for the springs. I spent a couple of the winter months calling different manufacturers. When I contacted Crower he asked if I was happy with the spring pressure I was running and I said yes, he then said continue to use it, and you won't have any problems, and they won't have to be rebuilt like others. They were right. I've also had a CC cam fail in yet a different motor. BTW I'm running 210lbs closed and 620lbs open pressures. Whenever my engine builder even mentions using something CC, I tell him give me my parts and I'll go elsewhere. The new engine has Ohio Crankshaft rotating assembly in it. Tall deck Dart block, and Dart 18 degree heads.
