Both oil seal were leaking badly along with a leak from the cam sensor housing (o-ring) so replaced all three (along with water pump). Camshaft seal really easy good access, cam sensor housing a bit more difficult.
Crankshaft seal, as i said stuffed the first one, access not that great i found it hard to see if i was pushing the seal on square with the engine and screwed it up by not noticing that the spring had fallen off with all my fiddling.

Cambelt change - The factory service manual is very comprehensive and there are workarounds where it calls for the special tools, only tool i had to get was a bigger torque wrench (torque settings are one thing that should not be guessed at I came across a few example of ruined crank/cam shafts from the pulleys/cogs being installed at wrong torque while investigating how to do a cambelt change).



That being said from what from i read online 13BB engines are some of the easiest to work on.
