Bit unsure here, are you saying oil is actually coming out of the phase plug connector on the side of the dizzy, and leaking between the base of the dizzy and the block ?
There should not really be any reason for the leak here, as it's not even a pressure fed area.
The dizzy has no seal in the base between the shaft and the body, just the std crushed iron particle bush, the outer body of the dizzy has a seal around it where it goes in the block.
Do you have any piccie ?
The only normal prob with dizzy is sometimes they pick up the top bush and spin it in the housing wrecking the dizzy body, I replace these with a oilite bush for a permanent fix.
I've got lots of dizzy bits so should be able to sort yours but something very odd, you 100% sure it's from where you say ?
