Car blowing oil out of the radiator reservoir

Hello, It is not up to the shop whether or not the vehicle is worth it, it is up to you. If you would like to keep it going, a head gasket on a single cam four cylinder (or even a twin cam) is not the end of the world. It does sound like a head gasket, but you could also have a cracked or warped cylinder head or engine block as well. Here is the other thing to consider. How much is a bus or plane ticket? Lastly, if the condition of the vehicle is poor, or less than "great for it's age", consider the cost of future repairs v. buying a used, low mileage corolla or civic.
