And I think in some engines, adjusting valve lash since hydraulic lifters didn’t become ubiquitous until later?
Many engines even up to the mid 2000’s also needed valve adjustments. Honda F-series engines are notorious for it. The only difference is improvements in metallurgy mean the valve seats no longer recess nearly as much, and thing like the Honda F22’s only need the adjustment every 60k or so rather than every 10.

Interesting. I thought I vaguely recalled some modern vehicle needing it. Every 60k isn’t too bad though. I think my 60s Datsun needed it more often.
