Do the oil additives stop oil leaks ?

not the ones that thicken the oil. but the one that are
supposed to
'swell' the seals ?

if so , any ideas on a 'good' one ?

I used the Wynne's gearbox one for a small leak from the change
lever on the auto box of my SD1 over 10 years ago, and it has
never leaked since. In that case it did work, so I wouldn't
dismiss them out of hand.

Ok , its the seal swell type that i am looking for , to add to
the
engine oil ..

It's the swell type I used. The change lever on the g/box is
sealed by an 'O' ring. Presumably it swelled the ring enough to
stop the leak.
I imagine it would work just as well for some seals in an engine,
but whether it would be as effective for all seal failures is
doubtful IMO.
