I built the engine myself, this is the first engine failure that I have ever had. The oil pressure always ran at 40 to 50 at 60 MPH. 20 at idle at 500 RPM. Have always run 40W to 50W oil, Delo 400 for first 1200 miles changed to Mobil 1 but changed back when it engine would not quit using oil. The 4600 mile trip used three gals of Delo 400. The pistons were not hurt just two broken top rings. The new rod bearings plastigaged out to .0015 on all six rods. Just got the engine running again and retorqued the head.
