2002 Saturn L300 Leaks here. What connects here?

From my Many years of experience working on those cars I would say the thermostat housing and or oil cooler plate next to thermostat housing is leaking.I they even changed the design of the thermostat housing to help stop it from leaking.I have replaced so many of those thermostat housings and resealed so many oil cooler plates I could do them in my sleep lol. We used to them both as the coolant leak repair. They even leak there on the caddy catera which uses the same engine. Have you pressure tested it yet to look for the leak?Because coolant runs funny on those when they leak. If the corner of the oil cooler plate closest to the belt or thermostat housing is leaking it can look like something else is leaking.
