91LS400vgb Posted October 9, 2006 Share Posted October 9, 2006 I've had a persistent small p/s leak since I purchased my 91 LS400 less than a year ago. The power steering pump, rack and high pressure hose were replaced right before I purchased the car. Originally, I thought I was losing fluid through the idle up valve so I replaced that. However, the leak continued and I now have discovered that a small amount of fluid is leaking from the high pressure hose underneath on the driver's side that is threaded into a steel line (see picture). It is seeping out from the threads. I have tried tightening the connection but it won't budge, so I'm not sure what to do. Should I loosen it and apply some kind of thread sealant? The other thought I had was adding a power steering leak additive as the leak is very small - but I'm concerned that may not be the best option in the long run. Any advice is appreciated. Thanks.
