And the answer is . . . .=20

Top choice:
leak from larger of 2 bolts holding front crank
sensor in place.  Nicely described by Brett Anderson
at http://www.koalamotorsport.com/m30oil.leak.htm

Second Choice:
replace oil pan gasket (probably a shop job, unless you
have a lift)

Other choices:
oil pressure sensor mounted to=20
     back of upper driver's side of head
valve cover gasket
timing chain tensioner on front
     passenger side of motor

Again, MANY thanks to all for the help.
