My 1988 f250 xlt lariat 5.8l

I have good knowledge of mechanical work. I had planned to pull the engine to do all the engine gaskets and make it nicer. Maybe delete the egr system. I have no idea how many miles are on it. And I am going to do the rust repair.

What's the best way to go about fixing my oil leaks? the whole bottom hald of the engine is covered so I can't tell where its coming from.
