Might have lost oil pick up?
Running a 496, built and dyoned by builder. THe motor has maybe 5 miles on it. Had it out the other day for a cruise and noticed my oil pressure was dropping to around 10. I managed to get it home and keep the rpms up to keep pressure up. Started it today and it had 60 lbs with me holding the motor at 1500-2000 until it would idle. Once idleing it slowly dropped from 40 to 20 then to 10 when the motor temp got to 150. Coild my pick up be sitting in the bottom of the pan? I'm going to drain the oil and see if i can hit the bottom of the pan and listen for the pickup, or put a coat hanger in there. Another question I have is when cranking the motor with the coil wire off, my oil pressure gauge (mech) would only show 10 pounds while cranking. One thing i noticed is that when I rev the motor the pressure goes up, but i'm hearing this high pitch noise that gets louder when you rev it.
