I am going to get burned for this but I have to say it. In our shop, we always tried Lucas power steering stop leak. We used it for both external and Internal leaks (internal caused Morning sickness). At least 80 percent of the time, it worked and some would last for years. Some only cost money. Once you are ready to pull the trigger, this is a cheap test. It may or may not work. We never saw it cause a problem or make a problem worse.

NO, I do not work for Lucas. I don't own stock in Lucas.
