You're unlucky with the seal tbh, or someone has replaced it with a seal which isnt a genuine bosch one as I know no one who's ever had an issue with seals and petrol after running a slight petrol mix. As Dan said, the nothc is inline with the wodruff key, you're doing well to get it back together on the car though!, much easier/cleaner/safer to just sack it off the motor though and get it on the bench... your grease will hold bits of shit in it and what not but best of luck
