The flat cam lobe problem has become pretty common
lately with the 4.0l's. It may be due to the removal of an additive
called ZDDP from modern engine oils. The additive was the main
ingredient that kept metal to metal friction from destroying parts in
older design flat tappet motors. The additive has the bad effect of
shortening the cat-converter life. The manufaturers have to provide
very long performance warrantees on the converters nowdays, so they
wanted the additive removed. "SM" rated oil is the type that has almost
no ZDDP in it. The Jeep 4.0l was perhaps the last engine still running
with a flat tappet cam!
Here's a link to an article in Hot Rod magazine: http://www.hotrod.com/techarticles/engine/flat_tappet_cam_tech/index.html
You might try searching for "ZDDP" and "cam failure' and you will see page after page of info on this!
