there are many products that say they stop oil leaks. i found that they can cost from 2 bucks a bottle to 24 bucks a bottle. they say they fix oil leaks for good. and that they will will not harm your car or clog it up. but most say that it only works on rubber seals. has anyone ever tried this stuff and if so does it work? any known problems? thanks
By the way what are all the rubber seals and gaskets on the opel engine?
