Review on Optimized BlueDevil Power Steering Leak Stopper by Terry Keown

In 40 years of caring for my friends and family, BlueDevil Power Steering Stop Leak is the first product I can remember that really and completely lived up to its name and promises. I simply followed the directions on the bottle and added about 3 ounces of product to the PS reservoir, which after continuous slow learning was already low (about 1 ounce per day). After a few hours of driving for 2 days, the level in the tank stopped falling. Since I topped it up slightly above the Max Cold level, it easily lost about 1 ounce. and stopped Max Cold right there. This problem started last winter after a long drive to and from Vermont in a 2009 Subaru Impreza. The PS pump was making quite a bit of noise, and I noticed that the liquid level in the reservoir was well below the Min Cold level, but was not yet empty (which would quickly destroy the PS pump). After filling the tank he started looking for leaks and found one on the back of the PS pump. It was leaking out of the high pressure switch very slowly. I kept topping up the tank each week when it hit the minimum cold mark. So when it got warmer, I replaced the PS pump. But the leak persisted, and not in the usual places, but at the ends of the power steering hoses. It turned out that the leak was from the steering rack seal on the driver's side. The repair involved replacing the steering rack, which cost over $1,000 in most cases. I did a little research online and found this BlueDevil Power Steering Stop Leak. The manufacturer's website says it will work if the seals just harden over time. If they were physically damaged it wouldn't help. I found such honesty refreshing. Reading the comments on this AZ site convinced me that the $12 payout was worth the risk. All other leak repairs (radiator, oil seals, air conditioning) work by trying to plug the source of the leak. And you usually clog the radiator/oil passages/AC. This works by softening the neoprene seals so they fit snugly against the shafts again. This happened and there were no more leaks. to what most motor oil bottles use. Then the user does not have to guess how much 1/3 of the bottle costs.
