Looks like the PCV went bad and forced oil out the seal... removing the PCV momentarily solved the massive oil leak. Made it an hour south with no issues but on the way home the leak returned. Thankfully got it home without damaging the engine. Means I need to take everything apart and do it all over again...plus the added bonus of clean everything under the truck that's coated in oil. Will be trying Mr gasket crank seal and a moroso oil pan gasket as the fel-pro stuff is starting to let me down.
