~REALLY~ low oil pressure Just got done w/ the fm11 install (sounds badass btw 
)
However, it has really, really low oil pressure.
When I 1st started it, it had 30-40psi, but as I let it sit, it dropped to 20psi. Well, I drove it about 20mins down to the gas station and back and the oil pressure at 45mph was 17-20psi
Now when I let it idle for about 10mins, the pressure drops to 10-15psi.
I did a Rollmaster double roller and ls6 oil pump during the swap. Now I thought that I 100% made sure the oil pump o-ring was seated correctly, but I'm guessing that its not (although I've never heard of the pressure being this low).
The car doesnt make any weird noises, no knocking, no pinging etc.
My guess is the o-ring. Any other theories out there?

Low oil pressure after that is a red flag for the O-ring. I don't know, but I would have thought it would be very low from startup. Then again, 40psi on cold startup is probaby lower than average.
