You have received good advice here so only consider my suggestion as one other option.
I have worked with epoxies for many years and never cease to be impressed at what can be achieved
The secret - as noted for other methods, is to get the area absolutely free of grease and oil using isopropyl ahcohol or wax and grease remover. If accessible, it never hurts to scuff the substrate to provide a better bond. There are many different epoxies (I use Botecoat) but even Araldite will do. Do NOT use polyester resin! There are different brands available from a parts store. Whatever you use, mix it thoroughly to get a spreadable consistency.
Though it can be used on its own, applied with a stiff brush or a spatula., an even better option is to combine the epoxy with a layer of suitable material like a thin metal sheet, or fibeglass cloth. Lay down some epoxy first, then the reinforcing layer, tamp it down and put more epoxy over the top.
Actually this is very easy to do and the repair will be stronger than the original metal.
Good luck with whatever you decide to do.

All well and good but the Araldite website says -30 to 65 Araldite(R) Standard 2 x 15ml
However if it will hold up at 80c that is still not high enough for comfort - my TM2 Combo often shows the metal temp of the engine above 80 on a hot day when stopped at the lights at idle or when the engine is stopped for a little while and the heat soak from deep in the engine starts to heat the extremities.
Just not worth the risk - in my younger days I have used it on hot stuff like radiator leaks and it always failed.

Apologies - you are correct. When recommending epoxy, I was swayed by my positive experiences using epoxy thickened with heat-tolerant fillers, one example of which was on the engine block of a damaged Gardner Diesel engine. Personally, I am not a fan of Araldite so I'm not sure why I even mentoned it
I used it to seal/refill the plug on a TD5 injector wiring loom after reading 80C max strength limit but stable but softened to 150C.
Funnily enough the replacement loom has never given me a problem in about 6 years so the loom is still hanging in the garage unused.( it must be the talisman effect. If you have a spare it will never fail).
