Keep in mind that 90+ percent of engine failures stem from cooling system problems. Does your engine have steel core ( or frost,or expansion) plugs? Is it worth trying to prevent any further internal corrosion of your block or head etc. from what you say the tin plated retainer for your thermostat had rotted away, so the inside of your block must also be slowly corroding. All that stuff helps to block up your radiator(don't forget to flush it, from top and bottom)
Yes I would recommend an inhibitor. An anti freeze type usually should be replaced yearly, whereas something like Fuchs engine coolant(German brand) might outlast you. (you mix it 50% with your rain water)

Hi Lynn
From what I am being told it is a good idea to use a corrosion inhibitor. One of our club members came around this morning and I showed him the stripped down head. He also suggested using an inhibitor and said as there were so many types in use to speak to Repco and they can advise what would be good inhibitor for the old girl.
I had the radiator rebuild 18 months ago and when I drained it before removing the head the water was still clear and clean, I will flush it doing the top and bottom before putting in the new thermostat and retainer. I know that when I filled the radiator it always seemed to find it's own level in the top tank after a drive.
I hope that after the head is shaved and all is back together I have solved the problem, but if there is still water in the oil after that then It means the engine coming out and stripping it down to find the leak. When my club friend had a look at the old gasket and head he suggested the head may not have been torqued down properly. Geez I hope that is all it was as if it is the block then I will be off the road for some time. Fingers crossed.
Thanks for all you good advice and suggestions.
Cheers
Tony
