Started up the 8 for the first time in 2 months and there is a big puddle of oil on my floor, fairly sure it's the upper pan gasket. I'm close to replacing the clutch, meaning the tranny is getting dropped. So much additional labor, in hours, would it be to do the upper and lower oil pan gaskets?

Also in the while your are in there department, what else should be replaced, keeping a budget in mind. TIA

Lower pan is easy enough. Just make sure you scrape off all of the old gasket and clean the pan real well. The upper pan gasket is a pain.
