started restore 50 chev coupe 216 motor. After driving about 30 miles, running good, oil pressure went to 0 just as I pulled in drive. Had been oiling well. Drained the oil (2nd time) while hot and got some old cork remnants. Has remote oil filter and so suspected a blockage. Checked the filter, housing, lines, tee fitting, oil pressure line, line from rockers, rocker tube, pulled pan & cleaned (not very dirty), replaced oil pump & blew all lines down below. STILL NO OIL FLOW UP TOP!& NO PRESSURE. How does oil distribution valve work that is on side of motor? Oil is pumping out of spring loaded cap when i pry it up but no oil flow out each of the other 2 holes?
