Or it makes the seal and lasts for a considerable time.
I believe K Seal has been tried along with a couple of other brands.
So far from posts it appears the radiator or head gasket.
I'm not a mechanic but wouldn't a HG failure show in other ways, loss of power, hard starting, that sort of thing? The car still pulls like a train, starts up clean i.e. no smoke, white or otherwise, no contamination in the oil etc.
So what might be worth a punt is to replace the radiator. I'll check it closely over the weekend for any dried stains etc.
Only one other observation to note and that's the mpg of the vehicle has dropped from around 44pmpg to 38 ish. This is from the onboard computer thing which I always question the readings....but something to pitch into the mix for the gathered kind folks.
Actually another observation...the main radiator there is a smaller radiator to the right as you look at the car from the front. I believe this is intercooler or oil cooler? There IS a small damp patch at the bottom of this but I was told its not linked or has anything to do with the water based cooling system of the car.
So back to the panel if you would be so kind.
Thank you all for your time btw.
