This might be obvious but it seems to me that step one is to eliminate the
bypass as a possibility, not just with a better spring, but block it.

I learned to never trust plastigauge. .0005 too tight on a race motor and
it's all over with. A street motor may not care though
but still reading plastigauge can be a matter opinion or interpretation
instead of a hard dimension.
Whatever became of the came bearing clearance point I read about, or lack
of cam bearings. That seemed the most plausible.
I also read something about a crack in a main casting that caused similar
symptoms.

I'm the guy with the TR250 oil pressure problem. I replaced my oil
pressure regulator spring with a HD one. The one I took out measured short
and the new one was longer than spec from Bentley. It helped, but after I
got well up to temp, pressure disappeared at idle and water boiled over.
I'm travelling for work this week, so I dropped off my car with my mechanic
friend with a new oil pump and some plastic gauge to check the bearing
clearance. I'll find out the status soon. This is more than a little
frustrating with Triumphest starting next week.

Did the guy with the oil pressure issue on his new 250 motor ever get this
sorted? inquiring minds want to know.
I'm hoping to do a repeat on the
San Diego mechanic with (300,000?) miles on his 250 and never did the bottom
end. In the Triumph magazine article he said he just does regular oil
changes with STP. I've shaved the head and a hotter cam so I may have
added
additional stress to the engine. my oil pressure hasn't deteriorated in 16
years of ownerhip.
