Metal adhesive
Posted: Wed Feb 29, 2012 3:38 pm
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.
