That's the first time I ever heard that! I have been running roller rockers since '98, and solid cams, flat tappet at first, then solid rollers, since 2000. Never had a problem like the one mentioned. Now, it's not a daily driver, but I do drive the car several times a week and over the weekends about 7 months out of the year. I pull the valve covers each spring to check the rockers and the lash. The rockers have been like new, and I usually dont even have to adjust lash. John
