Im trying to decide whether its worth doing work to my A4 facelift 1.8. Its long in the tooth at a V with 180k. It still runs sweetly, but I dont know when the cam was last done, its losing coolant steadily so Im assuming the pump may be on its way out. How much is a kit going to rush me is it going to be throwing money away? Is something else going to kill it imminently?
