2003 Nissan Maxima Oil leak

First check for places oil could have collected rom the previous leak. A hollow cross member under the engine is a good place to look. Oil could drip from that for a while.

If the leak continues, find a mechanic with a "smoke" machine. He can inject white non-toxic smoke at 2 psi into the oil dipstick tube, then look for the place(s) it seeps out.

Another tool is to add dye that turns bright yellow under a black light, but that works better when there is so much oil it's hard to tell where it's coming from.
