RE: Taking it apart. |

I read a letter in the last Summitt catalog (the Profeesor Overdrive section) and it was about the longevity of Roller Rockers. I was surprised to see they said they would only last 20 to 30 thousand miles. I use Crane solid adjustable rockers with solid lifters because I like simplicity and the "antiqueness" of adjustable valve lash, but I do also like the idea of Roller Rockers. I guess the question I have, is when they fail, do they come apart and leave all kinds of bits of roller needles, the rollers, etc to fly around through the engine? Some produciton cars use roller cams, but I would think that longevity isn't a problem there. What gives? |
