Well if they are right or not don't really matter because they certainly went the wrong way to determine the problem. If they found coolant in the oil there are more then one explanation for this a cracked block is the least common. Could be a headgasket which is typical an intake gasket. This is where the pressure test comes in to determine exactly which is the real problem.
Now certainly a new engine although expedicious and certainly more profitable would solve the problem.I would have to say start over new shop tell them your story and advise them that you want to know a new engine is needed and have them explain everything you want to know. You have a legal right to know the facts and have a expert diagnosis of your problem. Good luck
