[DeTomaso] Oil, re-hash

[asajay at asajay.com]

I'm thinking FALSE.  Although the cam may be broken in, there is the  
continuing problem of wear.  Reduce the amount of zinc and the wear  
will continue albeit not as rapid as a new cam and lifters with new  
(low ZDDP) oil.

I wonder how many new cars come with roller cams in them these days.
