Honda does not use a gasket. the factory guide says to use 3 bond or equivalent on clean mating surfaces. But in most cases a gasket will do better than sealer anyhow. Hope your repair held up. :)
I’ll bet you they stripped the drain plug bolt. Otherwise at that mileage there’s no way it would be off or leak otherwise. The front cavity goes under the front crank case and when I had mine off to replace the water pump mechanical seal it seemed apparent to me that it keeps the clutch bathed in oil as it resides at the front of the engine.
