Permatex 30302 Engine Oil - Stop Leak, 12 fl oz, Effectively Stops and Prevents Oil Leaks and Burning Without Needing to Dismantle

Had a small radiator leak on a Farmall Super A tractor.It’s holding up after about a year now. I’m very happy with the product.

My grand daughter borrowed my old 1989chevy one ton garden truck😖Lost serpentine belt - Her boy friend said it would be ok to drive it 18 miles back home.It has a blown head gasket- Do to the ago of truck all garage shops said scrape it.Installed the Permatex- The old girl is workingJust fine. strongly recommend this product

I had the gaskets replaced around 4 months ago and my engine is dripping little oil, tried the treatment, ran for 300 miles, then again for 100 checked oil and was low again, Its not big leak, but after a week you can notice a small puddle in the driveway.Burnt oil smell went awayMaybe a second bottle is needed. Keeping my hopes up. Dont want to dismantle the whole engine to find a gasket that was incorrectly seated.

Only worked for about a month that it started leaking again

I didn't follow the directions as they wanted. But it was good enough. The leak stopped.

Did not work for my 2012 VW Routan. I followed instructions and the product did not work and unable to return so money lost. Do not order and try a different product.

Easy to use. No clogging. Works great. I was seeing a lot of white smoke and having to top off my antifreeze before using it. Now there's no smoke and my antifreeze hasn't had to be topped off since. I wish it was cheaper, but it's a lot cheaper and easier than replacing a head gasket.

have a old Chevy truck with the intake gasket that goes bad and lets coolant leak into the oil pan. Used half a bottle and so far no more leaks. Would use this product again. Great product.
