Hi,
I have the same leak at about the same place -lower left corner of engine- in my 96 Camry DX (4 cyl. engine). I strongly suspect the leak comes from the oil pump seal (once the engine starts the leak starts, once it?s stopped, the leak stops)
However, I have been unable to remove the crankshaft pulley nut, so I cannot see exactly where the leak comes from. I wonder in what direction the nut loosens (looking at the pulley from its front , clockwise/counterclockwise)
I know it sounds stupid, but those are fastened quite hard sometimes and I have had not success so far... if anyone knows please help. Thanks
