While I was checking to see why the engine had dropped 200 RPM yesterday ,(
I described what I found in another post ). I noticed in only 1300 miles
since I cleaned the top on the engine case and replaced the runner boots
and all vacuum line and fuel lines that the top on the case on both sides
is wet with oil again. I even noticed the TPS bottom of the plastic cover
had engine oil drops on it. I know I didn't overfill the oil bath plus the
right side of the engine has no oil cooler and the case slopes down from
the center on both sides and I retorqued all the top case half bolts and
nuts. No idea where the oil is coming from. I don't see any oil squirting
oil while running hot or cold. I know the torque converter  fan blows air
at the top of the engine case which might spread it and the only place it
can leak oil on the top is the cooler . I know when I rebuilt it in 1997 I
sealed the case halves properly.   All I can do is remove the oil bath and
see what I can find  and wipe it off .
