'79 p/s leak



'79 p/s leak

Postby tonka » August 10th, 2010, 11:41 pm

So I had a one year old power steering valve return to pump hose blow and I replaced it. I then found the control valve to be leaking. Got a rebuild kit and it actually works! (rar!) I went ahead and replaced all the hoses even though I did that a year ago. Then it looked like I had a small weeper coming from the power steering cylinder but the more i look at it I think at least part of it is coming from the upper of two fittings on the cylinder. If I really dry it off I can see that fluid begins to show between the bolt part of the fitting and the steel line. It's not cross threaded and is tight, (somewhat short of gorilla tight). Gravity moves the fluid to the cylinder rod exit area so it looks like the cylinder. Do I need another freaking hose? No big deal but it is a pita and my goal is to have a non drippy car. My plan was to replace the cylinder seals but not so sure it's needed since I can see the fitting weeping. Any suggestions on this? It does not appear to be leaking between the threads of the fitting and the walls of the cylinder, if that makes sense.

theres several types of tubing connections, used in brakes and power steering connections,many use o-rings that can be replaced if damaged, but the seats must be clean and burr free

BANJO BOLTS ARE FREQUENTLY SUPPLIED WITH SIMPLE BRASS WASHERS, the RUBBER, INNER SEAL RING SEAL TYPE IS A BETTER CHOICE

in many cases leaks result from minor imperfections in the flare fittings, damaged, worn or badly made flares ,burrs or crud on the sealing surface of the flare or seat cone,damaged seats,, the wrong flare, angle or having the tubing not properly aligned while the fitting being tighten, in some cases leaks can be stopped with Teflon tape on the threads, but that's usually a band-aid approach
Some designs use O-RING seals , that must be properly installed,and if you screw up and pinch or miss-align a O-RING you can purchase kits with replacement O-RING seals

ID point out that they do make power steering leak seal products,personally Id also strongly suggest you AVOID THEIR USE, as Ive seen problems in the past with their use. but to be fair I know a few people that swear it works well.

As a follow up, I removed the hose checked it, cleaned it (already spotless) re seated it and still weeped from nut/steel line area. Bit the bullet and got another hose locally which went in and dried up the drip. I don't see any defects on what I removed, but problem solved for now.
