went offroading, now got oil issue and truck wont stay running

[BigBlocksRule]

Go to O'Reilley's and get an intake manifold temperature sender or scavenge one that you know is good. It's screwed into the intake beside the thermostat. Unplug the old one but leave it screwed in, plug the new one in and lay it on the intake. If that sensor is bad, it'll make it run rich, similar to the problems you've described, the new one should make it straighten right up. Also, check your PCV valve, you may be making crankcase pressure and having oil blown out by the gaskets.
