My first thought last night was to bodge it .
But having had sometime to think about it ,I decided to drop the engine out today.
What looked like a minor crack last night turned out to be a brake .
The whole mounting point has broken off just below the bolt hole .
Looking at the piece that has broken off ,
the aluminum is dark and oily only a small area on one side is bright so it's probably been cracked for sometime.
Andy230 ,
Aren't the head and cam cover machined as a pair ? Hence the matching numbers on them .
So I'll need to change the head as well ,If this is the case I lose a flowed head ,
But having looked at it I'm sure I could copy it using my dremel ...
