island4x4.

Found then, Part number STC4082EL Island 4x4 Thanks

Well
At last found the problem. three liners have slipped causing a right dent in the head gasket Causing a slight crack on one side of the gasket. Can see where the liners have been Hitting the gasket . So not going to bother to repair. Also there is a lot of play in the pistons and a lot of oil. So rings have gone as well. So will sell it as Is. Someone will like a project to replace the engine or fit top hats.
Sad really was a lovely ride
Thanks to all the Contributed to this post if anybody wants to buy one let me know

sorry news sadly i've gone down the replacement engine route, don't wanna do it again soon wasn't slipped liners for me, 'just' a cracked block

Would love to get it going again. But was told that the LPG conversion Would of contributed to the overheating causing the liners to slip and I have read the LPG engines run a lot hotter and being an older engine obviously couldn’t take it sad but there we go

Still got my 2.5 so have to be happy with that. Might see if I can swap the seats over. V8 seats were far more comfortable. But not sure the electrics there for them ??

i don't entirely agree with that. LPG does burn hotter, so the coolant has more heat to move, but if the radiator and viscous fan are in order, then you are good

if it overheated on LPG, it would have overheated on petrol anyways

Was a brand new pump and fan. I was told by LPG fitter they run about 30% hotter

Yes quite. And it did

30%!? My car normally runs at 91c with the stat fully open at ~96c - 30% would be 118c, thats just ridiculous

Sorry meant to be 3 deg hotter.

Pictures of the slipped liners ??

The seats should be the same unless you have a dt with out leather, it will depend on your becm there are two types low and high line, if high you should be ok but might need the becm telling they are there.

Could always have a word with v8developments about a recon engine.

Simply put.

No.

LPG does burn marginally hotter petrol burns at 1530 degrees C and LPG at 1550 C so hardly any difference at all, not enough difference to worry about. however what mainly contributes to RV8 dropping liners is incorrect fueling, running the V8 on either a too rich or lean mixture due to sensor failure etc will do far more damage that running it on a arguably better fuel.

LPG lets not forget is far better for an engine when compared to petrol, for one it is one of the purest fuels you can run very few impurities, and also the octane rating of over 100 means that 99% of the time an engine running on a properly done LPG conversion/Map will actually run smoother than when running petrol

I know mine does!

As long as your 2.5 has a Hi Line BECM you should be able to fit electric seats, I can't remember but they may need to be enabled with diagnostics.
