Oil pressure.
Trigger:
The pressure has increased as the Japanese worked out tighter tolerances. And today on modern engines all work on the same tolerances.
When i was a lot younger, people would say that British engineering was the best in the world, in later years when i trained at Honda i found it was a load of shite and Japanese engineering was far more superior ;)
K2-K6:
There's an old noted tale about these manufacturing ability that illustrates....to the question "what tolerance can you work to ? " the answer given was "what tolerance can you afford Sir" :)
It's certainly in the Japanese technical psychology to just keep pursuing those improvement in development, manufacturing and product resulting from those process.
Whats not even now aknowledged, and in the light of thinner oils being used in current engines to general disbelief....comments like "how can it possibly last long running on that thin an oil ? pfft, you'll not catch me using that stuff, I'll run it on 20w50 " when in reality these Honda engines, even in the sixties are specified and toleranced to run on straight 20 viscosity at ambient temperature up to 60 F and 30 viscosity above that. They were that far ahead in manufacturing tolerance right from the early engine.
Bryanj:
When i started in the merchant navy in 71 i joined a british built ship built in 53 with a 10 year life, the japanese built tankers with a 10 year life were scrapped at 12yrs.
They work strictly to design parameters instead of the british saying "that dont look right, make it thicker!"

Was that 1853 Bryan?
Was there a spec for the oak?

No only for the square rigged sails at that time. ☠ï¸â˜ ï¸â˜ ï¸
