Started the car yesterday for the first time since my little misshap.
It started and ran beautifully (made all the hairs on my arms stand to attention) Couldn't let it run for too long as there are no fans fitted yet (and the cardboard on the new rad probably wouldn't have helped cooling) But everything seems fine, oil pressure excellent, no obvious leaks (although I guess that may change when it gets warmed up)
Should be back on the road within a few weeks.
