Yes, I had more oil pressure before the rebuild but I didn't touch (let alone
change) the oil pressure relief value/spring. Now the pressure is low, so I
suppose, if it is the OPRV, then it must be due to it becoming blocked or
stuck rather than wear?
And, yes, the answer was air would make no difference to the pressure
reading, but I wouldn't know whether (or how) you could 'bleed' the line to
gauge?
Cheers

That's a lot of "what ifs". :)
I have a bad memory, so correct me if I'm wrong. Here's the way I remember
the issue:- he had more oil pressure before he rebuilt his engine- he
replaced the oil pressure relief valve ( or just the spring? ) as part of the
rebuild- His original question was regarding whether air in the line to the
gauge could be affecting things. "What if" he just put the old spring back in
so that he's comparing apples to apples? ( while perhaps comparing the 2
springs for length while they're both in his hand. I'm not sure how you would
compare the strength of the springs. Someone knows. )
I believe the response that he got to the "air in the line" question was that
"pressure was pressure", but I really don't think that it would hurt to try
that. We tend not to like air in our brake lines. So what do you have to
lose besides time? I'm really an ignoramus on these issues, but I was just
thinking ... I know, it doesn't become me! ;)
