Fuel in oil

[pwrdby4d]

I have a 1999.5 F250 4x4 7.3L w/ 87k on the odometer. I developed a steady oil drip on the driveway this weekend. Checked the oil level and its over full and smells like diesel fuel. I'm assuming its either an injector o-ring leaking or an injector has failed internally and the fuel is just leaking down into the crankcase. Is there an easy way to check the injectors @ home? The engine starts up easily and ran fine. Obviously I dont want to run it anymore till I get this figured out.

Thanks for the help, Wayne
