Has anyone ever tried a "stop leak" product in the power steering system to seal the rack drippings? Seems everyone has or will get a leak on it and as how it seems to be such a problematic arena for repairing it maybe some "chemical treatment" might pull it along for a few more years before the dreaded overhaul needs to take place. Shields are up for the incoming torpedos! | ||

In the UK Cliff. I just fit exchange racks.UK RHD are not too difficult to do. Did use a leak seal in a Jag auto box years ago, lasted about 100 miles and the seal went completely ! | ||

Cliff, Well, I'll be the contrarian: Why not? Most of these stop leak products for oil-based systems (and power steering that's ATF based qualifies) work by doing a "controlled attack" on the seals, causing them to swell on the surfaces where the product makes contact ever so slightly. I've never known of a single one of these to do damage and I have known of them to work. If they do, then you get to put off an expensive repair (and can budget for it while putting it off) until leaking returns at a later date. When it comes to things other than power steering (where pressurized fluid is mostly involved) I've seen some of these stop leak products effect a years-long fix. There's nothing to lose. Brian | ||

Cliff, which seal is leaking ? The pinion seal in my experience leaks for a little while and then fails big time. Have had this happen 3 times and always inconvenient with a recovery cost. | ||

Mark, Thanks very much for that input. These sorts of specifics are invaluable. My advice was very broad and general, but there are plenty of specific exceptions, and yours would be one of them. Brian | ||

Thank guys! I'm putting it up on a rack when I get back from holiday here in the top of the world :-) It looks to me that one end seal is dripping slightly. Just enough to be annoying on the garage floor (I put a cardboard square down under it to absorb the drips) There is a utube guy "project farm" who did quite a test piece on leak sealers that got me to thinking. He does a LOT of different testing and his methods seem proper. I'll be back :-) I'll report when I get it done | ||

Brian, do I recall that Richard Treacy did some posts on rebuilding racks and failures a while ago on this site. Mark | ||

Mark, Racking Your Brains by Richard Treacy is one I have pointed people to on numerous occasions. That being said, the question at this juncture didn't really focus on that aspect of things, so I simply tried to address the specific question asked. I have had success on more than one occasion with additives whose intent was to stop leaks if said leaks were not the result of seals that were "really, really far gone." Brian | ||

Thanks Brian, I have noted it, a useful article. Mark |
