sorry, scab is supercab, in '97 2 1/2 doors. I know this sucks. It's hard to believe they would design a motor you couldn't remove the oil pan on the truck, even if you had to raise it, remove other parts, etc. Yes, the dealer would kill you, 8 hours here is about $640 just to remove and replace the pan.
Were you talking about the rear main seal? The front seal? With a little luck you could probably do those without pulling the pan. Oil is very tricky to trace. Even if it drips from somewhere, the oil may be starting somewhere else. Just be sure.
I assumed you started removing the pan. Can you get it back in place from where you are?
