You've got that oil diverting pedestal in the front that I was asking about a while back. That's what is shooting the oil out there. My 250 doesn't have that pedestal but my 144's adjustable valvetrain does. I would check you're sending unit, gauge, or wiring/ground. Short the sending wire to ground to test the gauge, should peg it. Sometimes using teflon tape as a thread sealer can interfere with the ground connection for one wire sending units. I wouldn't recommend using teflon tape ever on an engine anyway if that was the problem, it can get into the motor. The color of the oil does seem off in the video, but you would know best about that, pull the filter and dump some out and have a look see.
Did you make that intake? Pretty cool.
