can't see that a small amount of lube would hurt , maybe engine oil, you are just trying to ease the thing into place without getting stuck, the o-ring is doing the sealing, the equivilent on the gearbox I oil freely when assembling
you just don't want to introduce anything into the engine that could block an oil way hence my suggestion of engine oil
