Have modern engines really abandoned flat tappets so universally?
I know the Jeep 4.0 isn't cutting-edge, but is it considered
so old that oil isn't mad for it any more?

The strokers list experiences might not be totally normalizable;
they're modding engines, right? With cam changes? Stronger
springs, bigger lifts?

Can't some of the oil-analysis services determine some of this
in post-mortems?

Umm, doesn't everybody? I go two years, if I'm really lazy,
three. I'm certain it's why my little air-cooled BW lasted 18
years/200K? miles. It probably had 6 - 8 fluid changes/band
adjustments in that time. I just had my A904 done at 25K miles
or so. Oil's cheaper than metal!

This iron of ours is getting old and exotic and expensive,
oil changes and maintenance are cheeeeep! (There's that Rambler
Mentality again.)
