What is the typical oil pressure that a "stock" 409 (dual 4) would run after it is warmed up. I think that I may have a problem. When I bring the rpms up the pressure goes up which is normal, but when it is at idle after warming it drops way low (according to the aftermarket guage in the car) I looked at the oil and it does look a little thin, but doesn't appear dirty or contaminated...Any help would be greatly appreciated. (BTW this is my first W motor and haven't had it very long and was supposedly rebuilt only about 1500 miles ago before I bought it.) Thanks
