It all depends on where and how bad the leak is. I used a power steering stop leak on a steering rack on my sons Astra, and it stopped the leak & held for two years until we sold the car (about 40,000 miles).Does this actually work? I tired one for a coolant leak and it never made a difference lol
Would wynns engine stop leak work?If it's definitely engine oil, I would try a bottle of this in the first instance. A lot cheaper than taking the gearbox out!
