oil that high is a pressurised leak in some hose or pipe or fitting
which is good news as that means relatively easy to fix once you figure out where it's from...

probably a busted oil pressure senseor
dunno what else is pressurized on the late motors
can't be the cam lines, at i don't think so , the cam lines couldn't spray to the back of the engine...

you might be able to see where it's spraying with the engine running...
else you'll have to track the leak from looking at the splatter marks.. CSI style...
