Cam Hardening |

Not sure.....but your original letter sounded like you had an "independant" guy re-machine the cam,... he might not be up on all the details of the hardening process. Any reputable cam company, such as Crane, etc, would be I am sure. The hardening would be very thin as the metal is exposed to a chemical bath and heat treatment. Obviously the chemicals dont' penetrate very far. So any maching would remove the hardened outer layer. The subsequent hardening might not be sufficient. The other letter about synthetic oil.....well, that can be true. That's why so many people insist on break-ins with mineral oil, and then switch to synthetic after a 1000 miles or more. |
