Range Rover Blues:
I'd say the 4.2 was more prone to "porous block sundrome" whcih is more cause d by the combination of running olean for economy and the auto box's insistance on straiing the engine rather than change down (for economy).

Tough wood I've never suffered and my 4.2 is home to a stick of Blackpool rock (5.0 TVR crank).

But it doesn happen to some poor unfortunates.  Iwas lead to believ it's more on the 4.0/4.6 enggines prior to the use of nickosil instead of a steel liner, but as I can't afford such things.....

I think it's more a thing for P38 owners though.

Spacemud:
James (jjsaul), thank you very much for the kind offer of help. It is always good to know that there is someone who has already solved your next potential problem!  :lol:

So far though, all is well. My water level light does keep coming on although the water level is fine, but I'm putting that down to a faut with the sensor....................unless you know different?

Engine/gearbox are great, swivels are clean, chassis is suprisingly solid. Interior is scruffy, especially the dash/gearstick conole parts where someone has used brute force instead of brains, so if anyone has spare brown interior parts for this model I may be interested.

Spacemud:
Ok, so the water level does seem to be dropping slowly (about a teacup every couple of days). I think it is the heater matrix as I took a look and it has obviously leaked at some stage and there is that slightly damp carpet smell. Fingers crossed I am right and it isn't the cylinder heads leaking.

It is LPG and I have heard that they tend to run a bit hot, could that be a contributing factor? The last lpg I had didn't lose water but lpg seems a bit of a unknown area still from what I read.

Any experiences of similar occurances?

Rossko:
The slightly increased flame temperature of LPG should have zero effect on engine temperature - bearing in mind the cooling system is designed to cope with a workout in Saudi and will just soak it up.

I have seen a couple of vaporisers fail internally and allow a serious water leak, killing the LPG operation.  Never seen one only seeping a bit, apart from at the obvious external hose joints and tees.  Check those thoroughly!

That said, there is more chance of many older LPG systems going out of tune and running lean - that could potentially cause overheating.

If you're happy it's reasonably in tune, I would just find and fix the obvious seeps (like the heater matrix) and see if that sorts it.

cheers, Ross K

Range Rover Blues:
And yes the senders are cack, disconnect it a bypass with something like a fuse.
