Oil leak (spotting when parked) persists. Installed new Oil Pan, old one was corroded through on bottom rear right corner. Checked engine thoroughly cannot see any leak. Any suggestions?

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.
