Hi guys.
I have a RRS, but did not get much answers there. I want to put a LPG in it and how are those engines handling it?
What would you put and give me just all I need to know.
I want to be safe.

Flashlube i think you need to use on the Jag engines. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
Mantec Sump Guard, Rigid Load liner, MY10 BT upgrade.

I asked around here a while ago. It didn't turn out to be economically viable over here, so I stopped researching. But I love the idea, for the range if nothing else.

Jaguar 4.4 valves are soft. You WILL need the valve protection liquid. I couldn't find out if that completely solved the problem or just made it less bad. (I'm very interested in the answer.)

I came across a company called JE Engineering that made hardened valve seats for the Jag 4.4. They seemed to think it was necessary along with using the valve fluid. I don't know.

I big problem I ran into is no one here had done a Jag 4.4 conversion! There seem to be a number of good UK mechanics with a lot of specialized knowledge on doing these. I would talk to a few of them and try to build a consensus.
