IS MY 2006 SY Ford Territory suitable for dual-fuel conversion using the Sequential Gas Injection LPG system. I've been told it will increase valve recession. My VS Commodore V6 had factory dual-fuel and the heads were rebuilt after 60,000km. I'm wondering if the Territory will suffer the same problem. Will a Flashlube valve-saver system ease the problem?
VALVE recession rises on engines running LPG because it's a dry fuel with none of the lubricating properties of petrol to protect the valves. Your Territory will be no different and my contacts suggest the head will need a rebuild at about 100,000km. I have no experience with the Flashlube system so I can't offer an opinion.
