There's been some discussion in the past regards reasons for low engine oil pressure, and one is a poor seal between the oil pressure relief plunger and the block (due to a weak spring or the metal to metal seal), allowing oil to bleed past the metal cup and back into the sump before doing its job.
Here's a note from www.spridget.com page 8 of their catalogue (both the big Healey and the wee one use the same design):
"Oil Pressure Relief – Note: Cup should be lapped in block, also grind spring as to stand vertical when placed on a table."
The lapping had occurred to me (as something to do during an engine rebuild) when I replaced the spring and cup and effectively resolved our low oil pressure problems, but the 'grind spring' is a new one to me.
