If the plug was an adjustment for the spring then there would be another means of sealing it .. thread sealant or some other separate seal like a high pressure turcon o-ring, etc.

looked like the plug bottomed out against a metal-to-metal tapered seal. Spring tension is not adjustable if this is the case.
