SOURCE: Oil leakage
You have an open hose from valve cover to no where which oil is coming out of....hmmmm, I would think yes..... If you still have a problem with oil blowing out of motor after those are fixed, sounds like you may have back pressure.

The fuel pressure should be 60 to 65psi in your system with the engine not running and fuel line primed, (ignition key's to the run position). Once engine is running the fuel pressure should drop by 5psi, change the fuel filter and recheck the fuel pressure at the shredder valve. it's known for the fuel pump to fail when the gas tank runs low or out of gas, the pump will end up burning it self out since the gas is what keeps the electric fuel pump cooled. The other thing to is putting gas through the top of the throttle body to start the engine on the SEFI is a NO NO, well a BIG NO NO. it's been know for the gas in the intake to catch fire and burn up the poppet valve in the injection system causing the replacement of the fuel injection system. Keep me posted and good luck, be gald to help you get your truck running again for the july 4th. OH and it was not mentioned but did the fuel filter get replaced???

what code is it?po440,p0455?If it is one of those codes it means you have a large evap system leak not a vacuum leak by the engine.the evap leak is most likely a inop vent valve or a fuel cap not properly sealing.

check the PCV valve, If its plugged you'll get the same results, most back pressure in motors of any type is oil pump, defective check valve in the filter section , try this, remove the PVC valve and the oil cap at the same time and block the vacuum line to the PVC hose, this eliminates the PCV system, and see if that reduces the back pressure, the only other thing it could be is bad rings ( just a note, did you recently start using synthetic oil ?)
