1999 F100 oil running out of engine above the oil pump. First replaced the oil pump to the newer model. Still leaking. Noticed the lower crankshaft oil seal seemed to be breaking down, replaced that, same result still leaking/pouring out. Engine was running good then started pouring the oil out. during a run. No obvious cracks, loose bolts, etc on bottom of engine.

did you check the crankshaft seal surface.
the shaft can be sleeved. -
found the problem
Found the problem. the lower main bearings have moved, causing the new oil seal to not work. Duh! Anyone need a 2001 f100 with bad main bearings. Located near Atlanta
