Getting head gasket replaced. New oil pump or just reseal?

What is your question?

got oil changed, couple days later smelled oil burning, saw oil under car. Suspected maybe overfilled oil, sotook it back to dealer. After they inspected said bot head gaskets were leaking. "it never made it to your reciept but on our copy it is noted by the mechanic that the leak was already there." Really?? 2 grand later and theyt wanna add new oil and h2o pump. could it have been the oil pump leaking the whole time and could it be caused by them putting in too much oil? any ininput would be greatly appreciated tnx, Ron
