why.............. finally got booked into r-tech, and the damn car broke down!!!! looks like a corroded water pipe let go, and blew a hole in it! and it happens to be one of the metal pipes that go into the block!!!!!! so have now got to run around to try and get it sorted before my r-tech appointment!!! am guessing its not going to be a cheap or easy fix??? dont suppose anyone has any knowledge of part numbers for the water pipe that runs under the inlet manni near the the thermostat housing????
