One Seal Stop Leak

I had a terrible power steering fluid leak, that my mechanic couldn't track down. I tried gallons of the Valvoline stop leak which did nothing. I tried a lot of the Lucas oil stop leak but all that did was make it leak more. Three bottles of this little stuff and I don't see a leak anymore.

This seemed to slow the leak in an older Kia Sportage and it was a decent leak. Did not stop it completely but it did help. I think the seals need replacement. But it definitely slowed it which works for now!

kinda surprised that it didn't last long 1

Ok…if you’re reading this then you’ve already searched the internet on whether or not this stuff is safe and/or if it works. As a mechanic, I generally like to take things apart and fix them properly but I have had such good luck with other Bars Leak products (Bars Leak radiator fix is truly amazing stuff )that I decided to give this a try. My issue was this. I had a zero turn mower that uses 20w50 full synthetic motor oil in its hydro’s. Most zero turns use a heavy viscosity motor oil which is why I went with the oil additive vs the hydraulic additive which Bars Leak also makes. Anyway, I had a hydro motor leaking ever so slightly. It would’ve been a huge job to take out and apart and I was pretty sure it was the same problem I’d had on another unit…a leaking o-ring on the low pressure side of the pump. Since this stuff softens the seals/o-rings and causes them to expand I figured it was perfect for the job. Well, it was. I put a little bit in the mowers reservoir and then mowed with it for about 45 minutes. I parked the machine on a piece of construction paper to let me know if I needed to add more or if the product failed. The next morning I came out annnnnnnnd……not a drop! It worked. For the price, this product is hard to beat. It’s inexpensive, easy to use and protects me from inadvertently running out of hydro oil.

I did an oil change for a 2004 Acura TL and use this because I had a small valve cover leak. 2 weeks later I had a misfire with a flashing check engine light. Had to change out my spark plugs/ignition coil and had to do an oil change again. Turned my oil to dark black and a smoking exhaust. My car is still burning off the black oil residue. Please avoid and do a valve cover gasket replacement or bring it to a shop if you're not mechanically incline.

I've used this stuff in 2 different vehicles with small oil leaks and it worked.

Seems to Work but I think I've got a ruptured hose that's leaking which needs to be replaced. I'll have to crawl under the vehicle and check it out, that's not easy at 77 years old ( dernit ) !

Muy bueno
