Fresh 8BA oil pressure problem

Watch the coolant.

I felt the same about the initial low pressure resulting from a possible faulty relief.

Smoke was lt. blue, just like during the initial run-in. My thought was too much oil on the fresh cylinders and new rings that may not be fully seated.

Oil is clean, and no water out the heads with the plugs removed.

A little nervous about any more running without a better understanding of what's going on. I ran it for about a minute after I noticed the 45 psi reading, trying to clean out the cylinders, without success.
