I have a 65 Chevelle that has a power steering leak. The leak comes from the seal as far as I can tell. It doesn't come from a leaky hose, all the hoses are fine. I've used the Bar's Stop Leak fluid for about a few months and have yet to see any results. How do you guys think I should fix this. Should I try to use the Lucas brand stop leak or should I try to replace the seal? I have no clue on what to do. So any help would be great.
Thanks in advance.

if this was mine, i would replace the seal or pump. i am not a great fan of stop leak products, the way i see it, if it will plug a hole,then it plug every orffice in what ever you put it in. besides all that, they are only a temporary fix anyway. good luck!

I would get a seal kit for the pump and overhaul it. i have a 67 chevelle with a big block and it leaked too. and a reman pump is a lot of money. i got a seal kit for the pump from Napa for about $13.00 and did is myself. just take your time and follow the instructions. It took me several hrs but its leak free and i painted it too so it looks like new. a reman pump can be very expensive.

It's been a while, but I believe your PS unit is a slave cylinder type with a control valve. The usual leak suspect is this valve with the slave piston rod seal being the backup suspect. If so, you probably need to rebuild the valve and the cylinder. Not a job for a novice but can be done. Even better, yank out the old junk and install a later unit that does not use the slave/control valve. I don't rember what year this change over occured, but that would be the year I would look for. Just take spindle, every thing attached to them, pump and PS unit.
