Was driving down highway at 65 mph. Instantly started throwing oil out backside of motor. Have inspected and can't find hole in block or any gasket failure. Is there a oil pressure line in this area? Would loss of oil cause low oil shut down?

It may be necessary to wash down the engine to pinpoint the source of the leak. For really hard to find leaks we use a florescent dye that you add to the oil, run the engine and then look for the dye to seep out a gasket, seal or mating surface using UV light.
