A variety of springs, and plungers were tried (known good) with no effect.
Side clearance of the plunger doesn't appear to be the issue. The
relationship of the drain hole to the depth of the seat might be. When
pressure increases, it forced the plunger out (under spring tension) far
enough that it passes the hole, and pressure is relieved by oil escaping
south into the pan.
It's a puzzler.

Ok,
1. have you measured the height of other springs and checked spring
tension with a scale or somesuch to see if somewhere along the line
someone bought a spring from Ace hardware that will fit but has
different specs? different wire thickness or spring rate?
2. Can you measure the diameter of the hole in the block? Insert a
drillbit or something to compare size at the thimble and at the pan
side?
