Very likely leaking at chain tensioner seal. Some use a fiber gasket, some seal with a rubber o-ring.

Bit of a job getting to it. AC compressor has to come out. Easiest to unbolt the bracket and just move it over. The bracket and compressor together are pretty heavy. IIRC the thermostat housing needs to be removed as well. If this hasn't been done for a long time, you may also need to replace the studs for the thermostat housing. Might as well plan on putting in a new thermostat while you are in that far.
