Honda distributors are definately the Achilles heel of their motors. After my friends car suffered from "red death" as some honda techs call it (100,000ks) I poped mine open to find the "red" occuring. Honda distributors dont have a sealed bearing, so the bearning gets hot and it rusts. finally the thing ceases and sometimes snaps your cam shaft if you are racing. I bought one of these. I think it will outlast the life of the motor from now on...
