My latest unmissable eBay purchase and bargain.OS 120 .Exhaust bend loose in cyl head,closer examination seems to indicate it had been glued in.Threads in cyl head very worn.New head too expensive .Any suggestions for a high temp compound that might give a fix,albeit a once and for all,never unscrew again solution.

Hi, Maybe the high temp silicone sealer used to seal joints on wood stove chimneys? I have never tried this so cannot guarantee it would work. Good luck with it.

I have had good results with J B Weld (original cold weld). steel epoxy.
So long as the metal is absolutely clean it sticks like snot to a horsehair blanket - and is hard and good for 300c.
Seems that it may now prove difficult to obtain which is a shame
If you can find some grab it - it is good.

There's an advert that appears regularly on the BMFA classifieds for stripped plug repairs, it may be worth contacting him. IIRC there's a fair bit of meat for a helicoil on the 120.

If you can't get the thread repaired, then JB Weld would be my recommendation but as Ace said, the parts must be clean.
