Bar's Leaks 1334-5PK One Seal Stop Leak - 11 oz, (Pack of 5)

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 is a great product.

I bought a few bottles for a few of my cars that had valve gasket leaks. It helped most of the vehicles and reduced the oil leaks. It did not stop them but it did noticably reduce the oil leaks at least 50% so it's worth it.

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!

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.

good product

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 ) !

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

يعمل بشكل جيد بعد صبه في محرك السيارة مع زيت جديد بدأت الاحظ بعد اسبوعين توقف التسرب من عدة اماكن كان بها تسريب وقل استهلاك الزيت بشكل ملحوظ جدا

Product does not function even on minor leaks that other brands working.
