Removing T4 engine - best way?

[Racemag]

I used some .5mm acrylic plastic sheet, cut and rolled a couple of times and placed into the centre of the seal. Then tapped this over the crank nose and slid seal along it and tapped it into place. There was an obvious groove in the crank nose from the previous seal - so this one was inserted a little less - may/may not work.
