Hello, new to this, got a question that I hope someone maybe able to answer or advise me on, I have a 2000 td5 and it's been leaking water on and off since I've had it really, it's had new radiator, water pump, every pipe going, thermostat and head gasket done, after the head was done it stopped for few months but then started again, there is a gurgling in the car when driving don't know if that's anything to do with it, just wondered if anyone could shed some light on this or has experienced same thing
