The bit that broke off is jammed in the Cam Angle Sensor (what I've always known as the distributor) shaft... ...if you pull it off and look into the shaft you can see some locator groves... ...and it's jammed in there...
The up side is that it is jammed in hard and won't come out... ...The down side is that I've been told it could last 10,000Km or 300,000Km before it fails totally...
Either way... ...it's better to learn now what I could do with it and what my options are before it fails...
