Gareth that sounds like better news. I heard from an older gentleman it may have something to do with head gasket but from what you are saying not likely. There hasn't been any missing coolant which is nice. The engine is generally quite oily I think I may have a minor leak somewhere but she still has plenty in her. With 175k on the clock and a 53 plate she's no spring chicken but she has been looked after with new discs and pads all round 2 new calipers and a proper service in last few months I've owned her so cost me a fair few bob. Hoping I can keep her running well for a few years yet. I won't be tearing anything apart atm need to degrease her properly and find the leak to start with.
Thanks aaron
