Worthwhile job just to stop the minor oil leak which on mine dripped onto the exhaust causing a smell, the gaskets harden following constant heat cycles, admittedly it's very fiddly but rewarding once completed, good to take your time!
Thanks guys. It was the nearside I did first so I've got the difficult side to do! I've had the the radiator top up tank off before so no worries there, it's just that secondary air pipe that looks like it'll be a pain again.
