I went out to the garage today to get the Nova out since it's quite nice outside and I was going to give her a bath. Well I started the car up and everything was fine, I was letting her warm up and the oil pressure was right in the 40-60psi range. After it warmed up and I took her for a ride the oil pressure dropped at idle to around 5psi!!!! I checked for leaks and found none. I then took the valve covers off of both heads and everything had oil on it. I'm stumped on this one. I would think that 5psi at idle is way to low or am I wrong?
