Ok so I have an oil leak from the left hand engine case , it would appear that the rubber grommet that seals the cables from the alternator is damaged,and they aren't available to buy without purchasing a complete alternator and loom assembly complete . Local dealer suggested silicon , but it was already covered in something and it hadn't worked,cost me most of the last day on a 3 day euro trackday , Phil Crowe doesn't have one , any ideas ?
