Metal adhesive

[corpy]

The incredibly slow refurbishment of the top end of my (trike) 1981 Z1100A1 engine is coming on, thanks to really useful help from members of this forum.
Yesterday, with a roll of drums, I replaced the cam cover and finally nipped it up this morning. The right-hand bolt halfway along the chain tunnel felt spongy almost immediately then slackened. The thin-walled casting has broken away, exposing the thread. Perhaps an over-long bolt was forced in sometime. The crack surface is dirty except for the final few mm at the bottom, so someone else had been there before me. Of course I should have seen it when the head was on the bench.
I am hoping that it is a blind hole i.e. that I haven't got an engine oil leakage problem.
The proper thing to do would be to remove the head and throw away its £50 Cometic gasket, have it welded up, re-machine it and so bloody on.
Is there a modern adhesive that would hold it back together?
I am hoping that the new gasket and the other 19 bolts will be able to seal the lid on.

At work i used this to do temporary repair to a casting holding a gear box and oil about 5 years ago. The gearbox leaked through the oil seals on the shaft. these were changed about two years after. i checked the repair it looked excellent and its still on going strong today.
whether its up to your job Corpy i cannot be sure but its worth a thought as it should stand a reasonable temperature and resists oil.

Iv'e used this also on lightly stressed areas with success - believe it or not I also repaired a alloy car cylinder head in the gasket fire wall sealing area it lasted 2 years !

Secret is to clean off all oil residues - carburetor cleaner is good for this
