[Shop-talk] engine rebuild

[Bob Spidell]

Forgot to mention there's a lot of concern about modern (SM) oils with 
little or no ZDDP to protect high-shear areas (like lifter faces and cam 
lobes) on flat-tappet engines.  There are several additives which add 
ZDDP, inc. GM "Eos," and it's important to use one during break-in.
