It is wise to degrease the engine first and then assess the oil leak(s). The lower ends on these motors usually held together pretty well. It was the cam seals and valve cover gaskets that started leaking oil in many cases, especially the rear bank that ran warmer. This can drip off the bell-housing and make it look like a rear main seal.
If the exhaust doesn't smoke, then your valve seals are probably OK.
Oil will leak down (gravity) and back (road draft), but with the wind turbulence at the rear of the engine, it can go everywhere.
A leak at the oil filter adapter/oil pressure sender at the front of the motor can blow back and look like an oil pan gasket leak.
