As others have said, a roller, yes if it looked ok. But anything else I wouldn't buy OR sell. Even if it looked perfect to both me and a buyer I would feel horrible if it then wiped and caused colateral damage to someone else's engine, even if I thought it might be their own fault. If I don't want a non roller cam anymore, it goes in the dumpster. They just aren't worth enough to take the chance. I won't even give it away. But that's just me I guess.

Oh Yea, I like the used underwear analogy also. Then again Bill Clinton gave his used underwear to charity and claimed it on his income taxes. Kinda gives me the Hebejebes.
