Engine is GA15de (1.5 litre chain driven camshaft) First symptom was sudden release of coolant from under the inlet manifold. Haven't got there yet to see what's gone - but it doesn't seem to be pipes from radiator to or from or around the pump, but I won't be able to see where without first removing the manifold. The water has lots (really lots) of oil in it - but there's no trace of water in the oil. Was running fine, oil / filters etc changed a couple of weeks ago - and not a hint of oil in the water then. Car was stopped immediately when the pipe went. It looks like it may have been blowing back into the header tank for a few minutes before it blew - there's a bit of oil in there too. I guess it has to be a head gasket, but before I rip it to pieces, is there anything else I should consider?
Thanks.
