RVS-Tec ferrro-silicate treatment - is it just vapour in the exhaust?

[Fast_Lane_Dane]

I saw yesterday a product named RVS (http://www.rvs-tec.com/English/index.htm) where the company claims that it can even out piston/cylinder bore surfaces and even reduce the 'gap' (don't know the exact tech English phrase here, sorry lads...) between piston and cylinder, thus enhancing the compression, even out differences in compression between the cylinders etc. etc.
I believe we all heard wonder stories from Fairy Land before about this and that amazing product, but the scientific explanation RVS gives actually is pretty waterproof - but: science and theories are one side, an engine overhaul is the other (The Dark) side, so before pouring the stuff down ind my old M116 V8, I would really appreciate to hear if someone on the forum has tried using RVS in engine/driveline and can give me a "yes, it's brilliant" or "DON'T, I blew my engine!" back.

Thanks a lot in advance,
Hans, DK

Hi Hans, A hard question , these things have been around for years and is nothing new, I do not think anyone here will have heard of it, or indeed tried it.

How bad is your engine.

Hi Malcolm,
The engine is not that bad, it runs a little uneven with just a tiny valve clatter, so I'm having the hydraulic valve lifters + ignition adjusted in the near future by a vintage Merc expert workshop I've been lucky to find .
It was more a case of preventive maintenance, since the car/engine is 25 y.o.

Cheers,
Hans
