Saved my engines twice!
Brilliant stuff and really does work. I tried it on my Landrover discovery and it stopped a leak that I suspect was a head gasket. I had a Volvo 940 Turbo that did have a head gasket problem. It worked on that too got another £10,000 miles out of it.

It works
Had what I believed was a head casket issue on the Jaguar X type. Previously took it to a garage that treated it with an unknown substance. The casket held for about 3 months before I had an issue again. Decided to do it myself with this product. So far so good, very little water loss, but not sure if that is the casket or just natural loss. Time will tell if this is a long term solution.
