It is probably from the threaded boss where the oil line is connected, they tend to get over tightened, split then leak.

I had the same issue on my Elford. I got it repaired by welding a new boss onto the rad, a decent ally fabrication company can do this for you. Always use an ally washer, copper is too hard.

s2 oil coolers are thin on the ground and pricey.... FC or TII coolers are the way to go...

Thanks for the advice guys. The connectors are sound, no leaks in that area. There is a slight leak somewhere in the matrix in the area near the big dent, bottom in pic below (maybe that's a clue ;) ). I'm going to try and keep things as OEM as possible, so will see if a local rad repair specialist can do anything;

I've just spoken to Paul at CRS and agreed to take the rad down for him to look at this pm. TBH, the rad is a bit of a mess! The core is shagged, but maybe end tanks salvageable? Maybe re-core? I've no idea, so let's see what they think....

Oil cooler now with CRS to rebuild. Should take about a week to do.

Cost was somewhat higher than I'd hoped, but as the guys there gave me some confidence in their workmanship - loads of great looking vintage rads to be seen - I decided to support what looks to be a good local business, rather than waste time seeking to save a few quid somewhere else.

Malcolm I phoned them up when I was looking to have my rad rebuilt, but like you I decided to use a local guy in Romford. It's like you say use the locals or they may not be there when you need them.
Good luck
