I checked the oil and coolant and did not notice anything unusual, but I don't think I'd be the best judge of that that either.
And could they determine this just from a 'visual inspection?'
I guess they could by looking at the oil and at the coolant?

Oh yes, and the dealer said that there is an oil leak, and they determined that it was because of the head gasket.
