Another power steering leak

I have had a browse through some of the many p/steering leak threads. After steam cleaning it all off this morning and then running her and turning side to side my leak is the seal where steering column enters the box.now my question is do I try Lucas stop leak or replace seal, I take it that behind the dust shield there will be a seal that doesn't look to bad to get at anyone done this seal and any opinions on stop leak additives cheers ..

Dont bother with stop leak. Just put 100ml ish of brake fluid in there. does the same thing

Someone I was talking to said do that but it didn't sound right, what does it do soften the seals up ....

Yeah makes em swell up to stop the leak. Mine loses all of its fluid in a couple of weeks. Gotta get round to doing it myself

Thankyou ill finish me bacon buttie and Add some brake fluid to the res. like you say worth a go and if not seal route next cheers for that
