	Just read about this stuff over on a Lotus Elise Forum. Now, I own 2 different cars, fitted with probably the 2 engines with the worst rep for HGF from the last 40 years, the Dolomite Sprint 16 valve, and the Rover K series. Any possible early detection of any problems would be of benefit. This stuff presumably reacts to any combustion gases in the coolant and changes colour, honks your horn and slaps you in the face if something is up. www.demon-tweeks.co.uk/Motorsport/Cooling_System/Coolant_&_Additives/Demon_Tweeks_4Life_Advanced_Engine_Coolant/1846/0/106223 Anyone have any experience with it?

	You can buy small kit sfor checking head gasket issues on E bay as well rather than running it all the time. We used to use them at Sercks on motors with distorted radiator tanks or 'unpeeled' plastic tank crimps.

	Early signs of HGF are usually immediately detectable, I can only see that confirming the overheating, oil/coolant mixing, pressurised header tank, etc., and on those reasons, I'm out. A simple detection of HGF on K-series is turning the key. I'm replacing a K-series on the MGF in 0 degrees by removing the subframe. I hate these engines more and more everyday - damn you Rover. There's people that give methods of avoiding it, but it's inevitable.
