Am I reading that right; your oil pressure was at 25 psi at cold idle when you first started it up?
I'm thinking you should be getting a lot more than that at cold idle. Somewhere in the 60-70psi neighborhood. I get around 65ish on startup on my freshly rebuilt KA (10W-40). Someone w/ an SR care to chime in?
Did you clean out the screen on the oil pickup well? possible restriction there? If you're not building adequate pressure that may explain the issue. Yeah pressure will go down to as low as 10-15 or so at idle with the motor fully warmed but the oil is hot at that point and at a lower viscosity. So you've got a higher flow for that pressure.

Sifted through a few posts there and seeing SRs showing higher cold startup oil pressure.
