If it is the thermostat seal, the rear coolant pipe where it enters the water pump housing, or the oil filter /cooler seal, they can be very hard to spot. If you have coolant dripping from the sump then it may well be the oil filter housing. None of them are trivial to repair. Oil and coolant leaks are these engine's signature.

Also check the coolant pipes bleed valves they can weep too.
