Bad Day, Very Bad day

Pulled the Valve Covers The white goo is only on the inside of the Valve Covers.(light coating) The rocker arms look clean and only VERY minor buildup around #3 cylinder valve spring. Pulled the distributor and the oil shaft will spin if I turn the engine over with the starter. Biggest Issue I can see is no oil pressure. drained oil and oil looks as clean as it came out of the bottle.Radiator fluid is only down about 4" from filler neck and coolant is clean and green. Not sure of where to proceed from here. Oil pump is a Melling High Volume pump and is about 3 yrs old. Motor probably has less than 30,000 since being bored .030 over. Engine has hydraulic lifters.
