Head Gasket on a BIS

[RicePuddin]

It has just come to my attention that there is a new product on the market thet fixes Head gaskets easily. It's called Steelseal. You pour it into your radiator (BIS only) and let the engine run for an hour or so and it finds it's own way to the damaged bit and seals it up permanently. Has anyone tried it? does it work?
There are some reviews on Youtube say that it does work.

With all these products they are a tempory fix, normally used for moody car sales to flog a knackred engine. The head gasket is the nearly the same price and with a couple of hours with the tools and a Haynes manual you would have fixed it.

I have heard about this product but I am quite skeptical of what it can achieve. As you know, there have been loads of products through the years that make huge claims. For example, oil and petrol additives that can improve a knackered engine's compression and stop oil leaks and there was a product that can fix radiator leaks just to name a few. All the aforementioned products would have been a phenonmenon, if it actually did what is said on the tin.

Head gasket failure is quite a serious thing, best to get it properly repaired. Using this would only be  a temporary fix. These radiator stop leak thingies are a gooy substance and once used it's best to flush the whole system as it can cause blockage (or partial blockage). Seen it where the gooy stuff was swimming around in the expansion tank...
I'm using an engine oil additive but i don't believe that it would give a worn motor huge power (using it just to make sure the oil consumption stays low)
