Hello! My car overheated when my wife was driving it recently, evidently badly because the mechanic here says that the head gasket blew. He's having to replace two lifters, all lubricants, several gaskets, and I don't know what else. I just two weeks ago replaced the the camshaft position actuator and the other sensor near it at the front of the motor, and also the oil pressure sensor on the driver side of the motor, all ACDelco since the car was throwing P014 and P016 codes. Yesterday he told me that the camshafpt position actuator, the one that you remove the power steering pump for (in case I don't really know what these parts are called!), will have been ruined by the overheating, and that I need to replace it. So my question is do I really need to replace this? It's a pain for me to get parts where I live, and it would delay the repair by some weeks. Thanks for your expert advice!
